PROJETO

Passo a Passo da Implementação da NeoSphere

1. Configuração do Ambiente de Desenvolvimento

Ferramentas Necessárias:

Python 3.10+ para backend Web2 (FastAPI, Redis).

Node.js 18+ para serviços Web3 e frontend.

Solidity para smart contracts.

Docker para conteinerização de serviços (Redis, MongoDB, RabbitMQ).

Truffle/Hardhat para desenvolvimento de smart contracts.

# Instalação de dependências básicas (Linux/Ubuntu) sudo apt-get update sudo apt-get install -y python3.10 nodejs npm docker.io

2. Implementação da API Web2 com FastAPI

Estrutura do Projeto:

/neosphere-api ├── app/ │ ├── __init__.py │ ├── main.py # Ponto de entrada da API │ ├── models.py # Modelos Pydantic │ └── database.py # Conexão com MongoDB └── requirements.txt

Código Expandido (app/main.py):

from fastapi import FastAPI, Depends, HTTPException from pymongo import MongoClient from pymongo.errors import DuplicateKeyError from app.models import PostCreate, PostResponse from app.database import get_db import uuid import datetime app = FastAPI(title="NeoSphere API", version="0.2.0") @app.post("/posts/", response_model=PostResponse, status_code=201) async def create_post(post: PostCreate, db=Depends(get_db)): post_id = str(uuid.uuid4()) post_data = { "post_id": post_id, "user_id": post.user_id, "content": post.content, "media_urls": post.media_urls or [], "related_nft_id": post.related_nft_id, "created_at": datetime.datetime.utcnow(), "likes": 0, "comments_count": 0 } try: db.posts.insert_one(post_data) except DuplicateKeyError: raise HTTPException(status_code=400, detail="Post ID já existe") return post_data @app.get("/posts/{post_id}", response_model=PostResponse) async def get_post(post_id: str, db=Depends(get_db)): post = db.posts.find_one({"post_id": post_id}) if not post: raise HTTPException(status_code=404, detail="Post não encontrado") return post

3. Sistema de Cache com Redis para NFTs

Implementação Avançada (services/nft_cache.py):

import redis from tenacity import retry, stop_after_attempt, wait_fixed from config import settings class NFTCache: def __init__(self): self.client = redis.Redis( host=settings.REDIS_HOST, port=settings.REDIS_PORT, decode_responses=True ) @retry(stop=stop_after_attempt(3), wait=wait_fixed(0.5)) async def get_metadata(self, contract_address: str, token_id: str) -> dict: cache_key = f"nft:{contract_address}:{token_id}" cached_data = self.client.get(cache_key) if cached_data: return json.loads(cached_data) # Lógica de busca na blockchain metadata = await BlockchainService.fetch_metadata(contract_address, token_id) if metadata: self.client.setex( cache_key, settings.NFT_CACHE_TTL, json.dumps(metadata) ) return metadata def invalidate_cache(self, contract_address: str, token_id: str): self.client.delete(f"nft:{contract_address}:{token_id}")

4. Smart Contract para NFTs com Royalties (Arquivo Completo)

Contrato Completo (contracts/NeoSphereNFT.sol):

// SPDX-License-Identifier: MIT pragma solidity ^0.8.20; import "@openzeppelin/contracts/token/ERC721/ERC721.sol"; import "@openzeppelin/contracts/access/Ownable.sol"; import "@openzeppelin/contracts/interfaces/IERC2981.sol"; contract NeoSphereNFT is ERC721, Ownable, IERC2981 { using Counters for Counters.Counter; Counters.Counter private _tokenIdCounter; struct RoyaltyInfo { address recipient; uint96 percentage; } mapping(uint256 => RoyaltyInfo) private _royalties; mapping(uint256 => string) private _tokenURIs; event NFTMinted( uint256 indexed tokenId, address indexed owner, string tokenURI, address creator ); constructor() ERC721("NeoSphereNFT", "NSPH") Ownable(msg.sender) {} function mint( address to, string memory uri, address royaltyRecipient, uint96 royaltyPercentage ) external onlyOwner returns (uint256) { require(royaltyPercentage <= 10000, "Royalties max 100%"); uint256 tokenId = _tokenIdCounter.current(); _tokenIdCounter.increment(); _safeMint(to, tokenId); _setTokenURI(tokenId, uri); _setRoyaltyInfo(tokenId, royaltyRecipient, royaltyPercentage); emit NFTMinted(tokenId, to, uri, msg.sender); return tokenId; } function royaltyInfo( uint256 tokenId, uint256 salePrice ) external view override returns (address, uint256) { RoyaltyInfo memory info = _royalties[tokenId]; return ( info.recipient, (salePrice * info.percentage) / 10000 ); } function _setTokenURI(uint256 tokenId, string memory uri) internal { _tokenURIs[tokenId] = uri; } function _setRoyaltyInfo( uint256 tokenId, address recipient, uint96 percentage ) internal { _royalties[tokenId] = RoyaltyInfo(recipient, percentage); } }

5. Sistema de Pagamentos com Gateway Unificado

Implementação Completa (payment/gateway.py):

from abc import ABC, abstractmethod from typing import Dict, Optional from pydantic import BaseModel class PaymentRequest(BaseModel): amount: float currency: str method: str user_metadata: Dict payment_metadata: Dict class PaymentProvider(ABC): @abstractmethod def process_payment(self, request: PaymentRequest) -> Dict: pass class StripeACHProvider(PaymentProvider): def process_payment(self, request: PaymentRequest) -> Dict: # Implementação real usando a SDK do Stripe return { "status": "success", "transaction_id": "stripe_tx_123", "fee": request.amount * 0.02 } class NeoPaymentGateway: def __init__(self): self.providers = { "ach": StripeACHProvider(), # Adicionar outros provedores } def process_payment(self, request: PaymentRequest) -> Dict: provider = self.providers.get(request.method.lower()) if not provider: raise ValueError("Método de pagamento não suportado") # Validação adicional if request.currency not in ["USD", "BRL"]: raise ValueError("Moeda não suportada") return provider.process_payment(request) # Exemplo de uso: # gateway = NeoPaymentGateway() # resultado = gateway.process_payment(PaymentRequest( # amount=100.00, # currency="USD", # method="ACH", # user_metadata={"country": "US"}, # payment_metadata={"account_number": "..."} # ))

6. Autenticação Web3 com SIWE

Implementação no Frontend (React):

import { useSigner } from 'wagmi' import { SiweMessage } from 'siwe' const AuthButton = () => { const { data: signer } = useSigner() const handleLogin = async () => { const message = new SiweMessage({ domain: window.location.host, address: await signer.getAddress(), statement: 'Bem-vindo à NeoSphere!', uri: window.location.origin, version: '1', chainId: 137 // Polygon Mainnet }) const signature = await signer.signMessage(message.prepareMessage()) // Verificação no backend const response = await fetch('/api/auth/login', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ message, signature }) }) if (response.ok) { console.log('Autenticado com sucesso!') } } return ( <button onClick={handleLogin}> Conectar Wallet </button> ) }

7. Estratégia de Implantação

Infraestrutura com Terraform:

# infra/main.tf provider "aws" { region = "us-east-1" } module "neosphere_cluster" { source = "terraform-aws-modules/ecs/aws" cluster_name = "neosphere-prod" fargate_capacity_providers = ["FARGATE"] services = { api = { cpu = 512 memory = 1024 port = 8000 } payment = { cpu = 256 memory = 512 port = 3000 } } } resource "aws_elasticache_cluster" "redis" { cluster_id = "neosphere-redis" engine = "redis" node_type = "cache.t3.micro" num_cache_nodes = 1 parameter_group_name = "default.redis6.x" }

Considerações Finais

Testes Automatizados:

Implementar testes end-to-end com Cypress para fluxos de usuário

Testes de carga com k6 para validar escalabilidade

Testes de segurança com OWASP ZAP

Monitoramento:

Configurar Prometheus + Grafana para métricas em tempo real

Integrar Sentry para captura de erros no frontend

CI/CD:

Pipeline com GitHub Actions para deploy automático

Article on How to install Angular on Ubuntu

Ubuntu is an open source operating system from the house of Linux. You will get security, support, and managed services from the publisher of Ubuntu with cutting age technology .To install Angular on Ubuntu, you first need to have Node.js and npm (Node Package Manager) installed . Then you will able install Angular at your system

Here's a step-by-step guide:

1. First install Node.js and npm :

- Open your terminal (Ctrl+Alt+T).

- Run the following commands to update your package index and install Node.js and npm. Wait for sometime , it may take a little bit time to install.

sudo apt update

sudo apt install nodejs

sudo apt install npm

2. To verify the installation of Node.js , run the following command

node -v

The terminal will return like this

v20.9.0

That means your node.js installation in successfull.

3. Now we need to Install Angular CLI 

- CLI stands for Command Line Interface

- In the Terminal type the following

sudo npm install -g @angular/cli

  It will also take some time

  To verify that Angular CLI has been installed successfully, run this command:

ng version

 or

ng v

- You should see output displaying the Angular CLI version, Node.js version, and other related information.

4. How to create a New Project ?

- After installing Angular CLI, you can create a new Angular project by navigating to the directory where you want to create the project and running:

ng new your-app-name

- Here  " your-app-name " should be you own app name.

5. A new project will be created . Several projects file automatically generated

your-app-name.css for writing style sheet

your-app-name.html for writing html

your-app-name.ts for writing typed script

you have to create new folder for images , videos other file if required.

6. Serve the Angular Application

- Once the project is created, navigate into the project directory:

cd my-angular-app

- Then, serve the application using the Angular CLI:

ng serve

- This command will build the application and serve it locally. You can access it by navigating to http://localhost:4200 in your web browser.

That's it! You have successfully installed Angular on your Ubuntu system. You can now start building Angular applications and i am sure you will love to work Angular in  Ubuntu.

I’m planning to write a sound change applier (like the one over at zompist) for conlanging purposes and probably written up on my conlanging/lingusitics/worldbuilding sideblog glossopoesis as bothj a useful project for my conlanging hobby, but also to help get me more proficient at coding which, given my actual job is definitely something I could use

plan is to duplicate all the functionality of the SCA2 on zompist (except for rewrite rules which, honestly are kinda pointless and I end up wasting more time trying to remember which way round it goes than it saves compared to just putting the changes in explicitly) which means substitution, environmental conditions, deletion, insertion, word boundaries, categories, simple metathesis, nonce categories, category-for-category substitutions, gemination, wildcards, glosses, option characters & exceptions. There are some other bits of functionality I’d quite like to add which are:

multiple exceptionsf

long-range metathesis (e.g. miraculum -> milagro)

explicit indexing of categories (i.e. T{i} > D{i} / _ Z{i} would send a member of category T to the corresponding member of category D when followed by the member of category Z)

updating categories during a set of sound changes (i.e. say you want to use h for a glottal at the start but for whatever reason a velar later, you can move it to the corresponding categories rather than having to leave it in the same one it’s in at the start)

surface filters that apply after ever normal sound change applied (these would also probably need to be able to be turned on and off during the course of the program)

both greedy and non-greedy wildcards (SCA2 has greedy wildcards that match any string only, but also having a wildcard that matches any one character would be useful)

wildcard blocking (i.e. a > æ / _ ... i unless ... includes N; is slightly different from a > æ / _ ... i / _ ... N ... i because the latter would also prevent atini from umlauting when it probably shouldn’t be blocked)

does anyone else have any suggestions on potentially useful features?

Also for code-ier people, any particularly strong feelings on what language to use? It’d need to be able to handle unicode and be fairly easy to develop in on a windows machine (although I suppose I could turn my old laptop into an ubuntu machine) but those are pretty much the only considerations. I suspect bash/awk is strictly speaking the best option here (seeing as awk is literally all about pattern substitution stuff) but for Personal Development reasons I’m leaning towards python or javascript/nodejs.

Nesse passo a passo estarei mostrando um exemplo de como integrar um chat bot GPT-3 que é uma API da OPENAI, que criou o ChatGPT.   Integrando Chat GPT com WhatsApp Para fazer esse procedimento estou usando um servidor com Debian (mas já testei o funcionamento com ubuntu 18...). A integração está sendo feita com: node.js venom-bot api da openai OBS IMPORTANTE: Nos testes que realizei, criei um servidor apenas para essa finalidade, se você não tiver conhecimento técnico suficiente para entender o que está sendo feito, sugiro que instale em uma maquina virtual. Neste exemplo, estou utilizando usuário "root" para fazer todo procedimento.   Instalando o node.js e atualizando o servidor Vamos começar atualizando o sistema e instalando node.js no servidor: sudo apt-get update -y && apt-get upgrade -y curl -fsSL https://deb.nodesource.com/setup_current.x | sudo -E bash - sudo apt-get update sudo apt install nodejs -y Depois disso, vamos instalar as dependências no servidor: sudo apt-get update sudo apt-get install -y gconf-service libasound2 libatk1.0-0 libatk-bridge2.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget libgbm-dev Após a instalações dessas bibliotecas, considere reiniciar o servidor. Prosseguindo, agora vamos instalar o venom-bot que será responsavel por conectar o chatbot ao WhatsApp: cd /root mkdir chatbot-whatsapp cd chatbot-whatsapp touch index.js npm i venom-bot No arquivo index, você vai colocar esse código: const venom = require('venom-bot'); venom .create() .then((client) => start(client)); function start(client) client.onMessage((message) => if (message.body === 'Olá' ); Agora teste o funcionamento e veja se o chatbot está funcionando digitando esse comando abaixo no terminal do servidor: node index.js Se estiver tudo certo, será exibido um QRCode para você autorizar o navegador dessa aplicação a usar o seu WhatsApp [caption id="attachment_1011" align="alignnone" width="300"] Exemplo de QRCode do chatbot[/caption] Depois disso, poderá testar digitando um "Olá" ou "Oi" para o WhatsApp conectado ao chatbot. E ele deverá responder pra você "Estou pronto!" [caption id="attachment_1012" align="alignnone" width="300"] Exemplo de resposta do chatbot[/caption] Se até essa etapa está tudo ok, podemos prosseguir.   Instalando a API do OPenAI e integrando com WhatsApp Agora vamos para integração com a api do openai, vamos fazer a integração do gpt-3 com o WhatsApp Para isso, vamos instalar a api do openai: cd /root/chatbot-whatsapp npm i openai Deverá criar um arquivo chamado ".env" com suas credenciais de acesso do openai (organização e api de acesso). OBS IMPORTANTE: é necessário se cadastrar no site da openai.com Depois disso poderá adquirir as informações nos seguintes links: OPENAI_API_KEY=https://platform.openai.com/account/api-keys ORGANIZATION_ID=https://platform.openai.com/account/org-settings Já o "PHONE_NUMBER=" é o numero do WhatsApp que você vai colocar no qrcode. touch .env echo "OPENAI_API_KEY=COLEAQUISUAAPI" >> /root/chatbot-whatsapp/.env echo "ORGANIZATION_ID=COLEAQUISUAORGANIZACAO" >> /root/chatbot-whatsapp/.env echo "PHONE_NUMBER=5511998765432@c.us" >> /root/chatbot-whatsapp/.env Agora você pode substituir o código do arquivo index, ou criar um novo arquivo para testar, neste exemplo estou criando um novo arquivo: touch gpt.js E deverá colocar o seguinte código nele: const venom = require('venom-bot'); const dotenv = require('dotenv'); const Configuration, OpenAIApi = requ

ire("openai"); dotenv.config(); venom.create( session: 'bot-whatsapp', multidevice: true ) .then((client) => start(client)) .catch((error) => console.log(error); ); const configuration = new Configuration( organization: process.env.ORGANIZATION_ID, apiKey: process.env.OPENAI_API_KEY, ); const openai = new OpenAIApi(configuration); const getGPT3Response = async (clientText) => const options = model: "text-davinci-003", prompt: clientText, temperature: 1, max_tokens: 4000 try const response = await openai.createCompletion(options) let botResponse = "" response.data.choices.forEach(( text ) => botResponse += text ) return `Chat GPT ??\n\n $botResponse.trim()` catch (e) return `? OpenAI Response Error: $e.response.data.error.message` const commands = (client, message) => const iaCommands = davinci3: "/bot", let firstWord = message.text.substring(0, message.text.indexOf(" ")); switch (firstWord) case iaCommands.davinci3: const question = message.text.substring(message.text.indexOf(" ")); getGPT3Response(question).then((response) => /* * Faremos uma validação no message.from * para caso a gente envie um comando * a response não seja enviada para * nosso próprio número e sim para * a pessoa ou grupo para o qual eu enviei */ client.sendText(message.from === process.env.PHONE_NUMBER ? message.to : message.from, response) ) break; async function start(client) client.onAnyMessage((message) => commands(client, message)); Agora teste o funcionamento e veja se a integração está funcionando digitando esse comando abaixo no terminal do servidor: node gpt.js Se estiver tudo certo, será exibido um QRCode para você autorizar o navegador dessa aplicação a usar o seu WhatsApp Depois disso, poderá testar digitando qualquer frase ou pergunta iniciando por "/bot" Então o bot vai responder você com a inteligência artificial configurada no código do arquivo gpt.js [caption id="attachment_1014" align="alignnone" width="300"] Resposta do chat gpt-3[/caption] Bom é isso, espero que esse passo a passo ajude você. Reiterando que utilizei um servidor somente para essa finalidade, ou seja, para fins de testes.

Instalar Node.js en Ubuntu

Introducción

Node.js es un entorno en tiempo de ejecución multiplataforma de código abierto, es una plataforma de código JavaScript del lado del servidor para programación de propósito general que permite a los usuarios crear aplicaciones de red rápidamente. Lo que simplemente significa que puede ejecutar código JavaScript en su máquina como una aplicación independiente, libre de cualquier navegador web. Al aprovechar JavaScript tanto en la parte del Front-end como en back-end, Node.js hace que el desarrollo sea más consistente e integrado.

Node.js se utiliza principalmente para crear aplicaciones de servidor de back-end, pero también es muy popular como una solución de pila completa y de front-end. npm es el administrador de paquetes predeterminado para Node.js y el registro de software más grande del mundo.

En esta guía, le mostraremos cómo comenzar a utilizar Node.js en un servidor Ubuntu 18.04. Aunque este tutorial está escrito para Ubuntu, las mismas instrucciones se aplican a cualquier distribución basada en Ubuntu, incluyendo Kubuntu, Linux Mint y Elementary OS.

Si necesita Node.js solo para implementar aplicaciones Node.js, la opción más sencilla es instalar los paquetes Node.js usando apt del repositorio de Ubuntu predeterminado o del repositorio NodeSource, en caso de que necesite las últimas versiones de Node.js y npm. Si está utilizando Node.js para propósitos de desarrollo, su mejor opción es instalar Node.js usando el script NVM.

Prerrequisitos

Esta guía asume que esta usando Ubuntu 18.04. Antes de comenzar, debe tener una cuenta de usuario no root con privilegios sudo configurados en su sistema.

Instalación de la versión Distro-Stable para Ubuntu

Ubuntu 18.04 contiene una versión de Node.js en sus repositorios predeterminados que puede usarse para proporcionar una experiencia consistente en múltiples sistemas. Al momento de escribir, la versión en los repositorios es 8.10.0. Esta no será la última versión, pero debe ser estable y suficiente para una rápida experimentación con el idioma.

Para obtener esta versión, puede utilizar el administrador de paquetes apt. Actualice el índice de su paquete local escribiendo:

$ sudo apt update

Instalar Node.js desde los repositorios:

$ sudo apt install nodejs

Si el paquete en los repositorios satisface sus necesidades, esto es todo lo que necesita hacer para configurar Node.js. En la mayoría de los casos, también querrá instalar npm, el administrador de paquetes Node.js. Puedes hacerlo escribiendo:

$ sudo apt install npm

Esto le permitirá instalar módulos y paquetes para usar con Node.js.

Debido a un conflicto con otro paquete, el ejecutable de los repositorios de Ubuntu se llama nodejs en lugar de node. Tenga esto en cuenta mientras ejecuta el software.

Para verificar qué versión de Node.js ha instalado después de estos pasos iniciales, escriba:

$ nodejs -v

Una vez que haya establecido qué versión de Node.js ha instalado desde los repositorios de Ubuntu, puede decidir si desea trabajar con diferentes versiones, archivos de paquetes o administradores de versiones. A continuación, analizaremos estos elementos, junto con métodos de instalación más flexibles y sólidos.

Instalación utilizando un PPA

Para obtener una versión más reciente de Node.js, puede agregar el PPA (archivo de paquete personal) mantenido por NodeSource. Esto tendrá versiones más actualizadas de Node.js que los repositorios oficiales de Ubuntu, y le permitirá elegir entre Node.js v6.x (compatible hasta abril de 2019), Node.js v8.x (la versión actual). Versión LTS, admitida hasta diciembre de 2019), Node.js v10.x (la segunda versión actual de LTS, admitida hasta abril de 2021), y Node.js v11.x (la versión actual, admitida hasta junio de 2019).

Primero, instale el PPA para poder acceder a su contenido. Desde su directorio de inicio, use curl para recuperar el script de instalación para su versión preferida, asegurándose de reemplazar 10.x con su cadena de versión preferida (si es diferente):

$ cd ~ $ curl -sL https://deb.nodesource.com/setup_10.x -o nodesource_setup.sh

Puede inspeccionar el contenido de este script con nano (o su editor de texto preferido):

$ nano nodesource_setup.sh

en mi caso lo hare con sublime text

$ subl nodesource_setup.sh

Ejecute el script bajo sudo:

$ sudo bash nodesource_setup.sh

El PPA se agregará a su configuración y su caché de paquete local se actualizará automáticamente. Después de ejecutar el script de configuración desde Nodesource, puede instalar el paquete Node.js de la misma manera que lo hizo anteriormente:

$ sudo apt install nodejs

Para verificar qué versión de Node.js ha instalado después de estos pasos iniciales, escriba:

$ nodejs -v

[Salida] v10.14.0

El paquete nodejs contiene el binario nodejs y npm, por lo que no necesita instalar npm por separado.

npm utiliza un archivo de configuración en su directorio de inicio para realizar un seguimiento de las actualizaciones. Se creará la primera vez que ejecute npm. Ejecute este comando para verificar que npm esté instalado y para crear el archivo de configuración:

$ npm -v

[Salida] 6.4.1

Para que funcionen algunos paquetes npm (por ejemplo, aquellos que requieren compilar código de origen), deberá instalar el paquete build-essential:

$ sudo apt install build-essential

Ahora tiene las herramientas necesarias para trabajar con paquetes npm que requieren la compilación de código de origen.

Instalación utilizando NVM

Una alternativa a la instalación de Node.js con apt es usar una herramienta llamada nvm, que significa “Node.js Version Manager”. En lugar de trabajar a nivel de sistema operativo, nvm funciona a nivel de un directorio independiente dentro de su directorio de inicio. Esto significa que puede instalar varias versiones autocontenidas de Node.js sin afectar a todo el sistema.

El control de su entorno con nvm le permite acceder a las versiones más recientes de Node.js y retener y administrar las versiones anteriores. Sin embargo, es una utilidad diferente de apt, y las versiones de Node.js que administra con ellas son distintas de las versiones que administra con apt.

Para descargar el script de instalación nvm desde la página de GitHub del proyecto, puede usar curl. Tenga en cuenta que el número de versión puede diferir de lo que se resalta aquí:

$ curl -sL https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh -o install_nvm.sh

Inspeccione el script de instalación con nano:

$ nano install_nvm.sh

Ejecuta el script con bash:

$ bash install_nvm.sh

Instalará el software en un subdirectorio de su directorio de inicio en ~/.nvm. También agregará las líneas necesarias a su archivo ~/.profile para usar el archivo.

Para obtener acceso a la funcionalidad nvm, deberá cerrar la sesión y volver a iniciarla o buscar el archivo ~/.profile para que su sesión actual conozca los cambios:

$ source ~/.profile

Con nvm instalado, puede instalar versiones aisladas de Node.js. Para obtener información sobre las versiones de Node.js que están disponibles, escriba: $ nvm ls-remote

[Salida] … v8.11.1 (Latest LTS: Carbon) v9.0.0 v9.1.0 v9.2.0 v9.2.1 v9.3.0 v9.4.0 v9.5.0 v9.6.0 v9.6.1 v9.7.0 v9.7.1 v9.8.0 v9.9.0 v9.10.0 v9.10.1 v9.11.0 v9.11.1 v10.0.0

Como puede ver, la versión actual de LTS en el momento de escribir esto es v8.11.1. Puedes instalar eso escribiendo:

$ nvm install 8.11.1

Por lo general, nvm cambiará para usar la versión instalada más recientemente. Puede decirle a nvm que use la versión que acaba de descargar escribiendo:

$ nvm use 8.11.1

Cuando instala Node.js usando nvm, el ejecutable se llama nodo. Puede ver la versión que está utilizando actualmente el shell escribiendo:

$ node -v

[Salida] v8.11.1

Si tiene varias versiones de Node.js, puede ver qué se instala al escribir:

$ nvm ls

Si desea predeterminar una de las versiones, escriba:

$ nvm alias default 8.11.1

Esta versión se seleccionará automáticamente cuando se genere una nueva sesión. También puedes referenciarlo por el alias así:

$ nvm use default

Cada versión de Node.js hará un seguimiento de sus propios paquetes y tiene npm disponibles para administrarlos.

También puede hacer que npm instale paquetes en el directorio ./node_modules del proyecto Node.js. Use la siguiente sintaxis para instalar el módulo Express:

$ npm install express

Si desea instalar el módulo globalmente, poniéndolo a disposición de otros proyectos con la misma versión de Node.js, puede agregar la marca -g:

$ npm install -g express

Esto instalará el paquete en:

~/.nvm/versions/node/node_version/lib/node_modules/express

La instalación global del módulo le permitirá ejecutar comandos desde la línea de comandos, pero tendrá que vincular el paquete a su esfera local para solicitarlo desde un programa:

$ npm link express

Puede aprender más sobre las opciones disponibles para usted con nvm escribiendo:

$ nvm help

Eliminando Node.js

Puede desinstalar Node.js usando apt o nvm, dependiendo de la versión que desee seleccionar. Para eliminar la versión distro-estable, deberá trabajar con la utilidad apt en el nivel del sistema.

Para eliminar la versión distro-estable, escriba lo siguiente:

$ sudo apt remove nodejs

Este comando eliminará el paquete y conservará los archivos de configuración. Estos pueden serle de utilidad si tiene la intención de volver a instalar el paquete más adelante. Si no desea guardar los archivos de configuración para su uso posterior, ejecute lo siguiente: sudo apt purge nodejs

This will uninstall the package and remove the configuration files associated with it.

As a final step, you can remove any unused packages that were automatically installed with the removed package:

$ sudo apt autoremove

Para desinstalar una versión de Node.js que ha habilitado con nvm, primero determine si la versión que desea eliminar es la versión activa actual: nvm current

Si la versión a la que te diriges no es la versión activa actual, puedes ejecutar:

$ nvm uninstall node_version

Este comando desinstalará la versión seleccionada de Node.js.

Si la versión que desea eliminar es la versión activa actual, primero debe desactivar nvm para habilitar sus cambios:

$ nvm deactivate

Ahora puede desinstalar la versión actual usando el comando de desinstalación anterior, que eliminará todos los archivos asociados con la versión específica de Node.js, excepto los archivos en caché que se pueden usar para la reinstalación.

Conclusión

Hay varias maneras de comenzar a utilizar Node.js en su servidor Ubuntu 18.04. Sus circunstancias determinarán cuál de los métodos anteriores es mejor para sus necesidades. Mientras que usar la versión empaquetada en el repositorio de Ubuntu es el método más fácil, usar nvm ofrece flexibilidad adicional.

Nesse passo a passo estarei mostrando um exemplo de como integrar um chat bot GPT-3 que é uma API da OPENAI, que criou o ChatGPT.   Integrando Chat GPT com WhatsApp Para fazer esse procedimento estou usando um servidor com Debian (mas já testei o funcionamento com ubuntu 18...). A integração está sendo feita com: node.js venom-bot api da openai OBS IMPORTANTE: Nos testes que realizei, criei um servidor apenas para essa finalidade, se você não tiver conhecimento técnico suficiente para entender o que está sendo feito, sugiro que instale em uma maquina virtual. Neste exemplo, estou utilizando usuário "root" para fazer todo procedimento.   Instalando o node.js e atualizando o servidor Vamos começar atualizando o sistema e instalando node.js no servidor: sudo apt-get update -y && apt-get upgrade -y curl -fsSL https://deb.nodesource.com/setup_current.x | sudo -E bash - sudo apt-get update sudo apt install nodejs -y Depois disso, vamos instalar as dependências no servidor: sudo apt-get update sudo apt-get install -y gconf-service libasound2 libatk1.0-0 libatk-bridge2.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget libgbm-dev Após a instalações dessas bibliotecas, considere reiniciar o servidor. Prosseguindo, agora vamos instalar o venom-bot que será responsavel por conectar o chatbot ao WhatsApp: cd /root mkdir chatbot-whatsapp cd chatbot-whatsapp touch index.js npm i venom-bot No arquivo index, você vai colocar esse código: const venom = require('venom-bot'); venom .create() .then((client) => start(client)); function start(client) client.onMessage((message) => message.body === 'Oi') client .sendText(message.from, 'Estou pronto!') .then((result) => console.log('Result: ', result); //retorna um objeto de successo ) .catch((erro) => console.error('Erro ao enviar mensagem: ', erro); //return um objeto de erro ); ); Agora teste o funcionamento e veja se o chatbot está funcionando digitando esse comando abaixo no terminal do servidor: node index.js Se estiver tudo certo, será exibido um QRCode para você autorizar o navegador dessa aplicação a usar o seu WhatsApp [caption id="attachment_1011" align="alignnone" width="300"] Exemplo de QRCode do chatbot[/caption] Depois disso, poderá testar digitando um "Olá" ou "Oi" para o WhatsApp conectado ao chatbot. E ele deverá responder pra você "Estou pronto!" [caption id="attachment_1012" align="alignnone" width="300"] Exemplo de resposta do chatbot[/caption] Se até essa etapa está tudo ok, podemos prosseguir.   Instalando a API do OPenAI e integrando com WhatsApp Agora vamos para integração com a api do openai, vamos fazer a integração do gpt-3 com o WhatsApp Para isso, vamos instalar a api do openai: cd /root/chatbot-whatsapp npm i openai Deverá criar um arquivo chamado ".env" com suas credenciais de acesso do openai (organização e api de acesso). OBS IMPORTANTE: é necessário se cadastrar no site da openai.com Depois disso poderá adquirir as informações nos seguintes links: OPENAI_API_KEY=https://platform.openai.com/account/api-keys ORGANIZATION_ID=https://platform.openai.com/account/org-settings Já o "PHONE_NUMBER=" é o numero do WhatsApp que você vai colocar no qrcode. touch .env echo "OPENAI_API_KEY=COLEAQUISUAAPI" >> /root/chatbot-whatsapp/.env echo "ORGANIZATION_ID=COLEAQUISUAORGANIZACAO" >> /root/chatbot-whatsapp/.env echo "PHONE_NUMBER=5511998765432@c.us" >> /root/chatbot-whatsapp/.env Agora você pode substituir o có

digo do arquivo index, ou criar um novo arquivo para testar, neste exemplo estou criando um novo arquivo: touch gpt.js E deverá colocar o seguinte código nele: const venom = require('venom-bot'); const dotenv = require('dotenv'); const Configuration, OpenAIApi = require("openai"); dotenv.config(); venom.create( session: 'bot-whatsapp', multidevice: true ) .then((client) => start(client)) .catch((error) => console.log(error); ); const configuration = new Configuration( organization: process.env.ORGANIZATION_ID, apiKey: process.env.OPENAI_API_KEY, ); const openai = new OpenAIApi(configuration); const getGPT3Response = async (clientText) => const options = model: "text-davinci-003", prompt: clientText, temperature: 1, max_tokens: 4000 try const response = await openai.createCompletion(options) let botResponse = "" response.data.choices.forEach(( text ) => botResponse += text ) return `Chat GPT ??\n\n $botResponse.trim()` catch (e) return `? OpenAI Response Error: $e.response.data.error.message` const commands = (client, message) => const iaCommands = davinci3: "/bot", let firstWord = message.text.substring(0, message.text.indexOf(" ")); switch (firstWord) case iaCommands.davinci3: const question = message.text.substring(message.text.indexOf(" ")); getGPT3Response(question).then((response) => /* * Faremos uma validação no message.from * para caso a gente envie um comando * a response não seja enviada para * nosso próprio número e sim para * a pessoa ou grupo para o qual eu enviei */ client.sendText(message.from === process.env.PHONE_NUMBER ? message.to : message.from, response) ) break; async function start(client) client.onAnyMessage((message) => commands(client, message)); Agora teste o funcionamento e veja se a integração está funcionando digitando esse comando abaixo no terminal do servidor: node gpt.js Se estiver tudo certo, será exibido um QRCode para você autorizar o navegador dessa aplicação a usar o seu WhatsApp Depois disso, poderá testar digitando qualquer frase ou pergunta iniciando por "/bot" Então o bot vai responder você com a inteligência artificial configurada no código do arquivo gpt.js [caption id="attachment_1014" align="alignnone" width="300"] Resposta do chat gpt-3[/caption] Bom é isso, espero que esse passo a passo ajude você. Reiterando que utilizei um servidor somente para essa finalidade, ou seja, para fins de testes.
