Chrome ExtensionをTypeScriptとReactで作る環境を構築する

Chrome拡張機能を作るときの環境をいい感じにしてみます。

最終的なディレクトリ構造はこんな感じになります。

env-extension ├── dist // 拡張機能として読み込むディレクトリはこれ ├── public │ ├── index.html │ └── manifest.json ├── src │ ├── background │ │ └── background.ts │ ├── content │ │ ├── content.scss │ │ └── content.tsx │ └── popup │ └── index.tsx ├── gulpfile.js ├── package-lock.json ├── package.json ├── tsconfig.json └── webpack.config.js

npmの環境を作る

ディレクトリを作ってnpmの初期化を行います。

$ mkdir env-extension && cd env-extension $ npm init -y

React + TypeScript環境を作る

必要なパッケージを落っことします。

$ npm install --save-dev webpack webpack-cli html-loader html-webpack-plugin file-loader ts-loader typescript @types/react @types/react-dom copy-webpack-plugin $ npm install react react-dom

パッケージを軽く整理してみる。

webpack

モジュールバンドラー。JavaScriptファイルをブラウザで動くようにするために必要。

webpack-cli

webpackのコマンドセット。

file-loader

importやrequireで読み込まれるファイルを��力先のディレクトリに配置する

html-loader

htmlをstringにして出力する

html-webpack-plugin

htmlファイルの作成を簡単にする。

copy-webpack-plugin

すでにあるファイルやディレクトリを、ビルドディレクトリにコピーする

ts-loader

webpackについてのTypeScriptLoader

typescript

TypeScriptへの対応に必要

@types/react, @types/react-dom

reactのための型定義が入ってるパッケージ

tsconfig.json、webpack.config.jsを作成します。 webpackの中身はあとで！

// tsconfig.json { "compilerOptions": { "outDir": "./dist/", "allowSyntheticDefaultImports": true, "sourceMap": true, "noImplicitAny": true, "module": "esnext", "moduleResolution": "node", "target": "es5", "lib": [ "es5", "es6", "dom" ], "jsx": "react" }, "include": [ "./src/**/*" ] }

ChromeExtension用のファイルを用意

popup

popupにはhtmlとjsファイル双方必要なので用意。

src/popup/index.tsxを作成します。

// src/popup/index.tsx import React from 'react'; import ReactDOM from 'react-dom'; const Popup = () => <h1>Hello world</h1>; ReactDOM.render(<popup></popup>, document.getElementById("root"));

// public/index.html <meta charset="utf-8"><title>env test</title><div id="root"></div>

background

とりあえず確認のためのスクリプトを挟み込んでおきます。

// src/background/background.ts console.log("background test");

content

スタイルシートなしで、確認できるようにボタンを配置しておきます。

// src/content/content.tsx import React from 'react'; import ReactDOM from 'react-dom'; const Button = () => <button>Hello</button>; const app = document.createElement('div'); app.id = 'extension-button'; document.body.appendChild(app); ReactDOM.render(<button></button>, app);

manifest

manifestを作成します。今回は確認のためだけの最小限に留めます。

// public/manifest.json { "manifest_version": 2, "version": "0.0.1", "name": "env-sample", "description": "sample", "browser_action": { "default_popup": "index.html" }, "background": { "scripts": [ "background.js" ] }, "content_scripts": [ { "matches": [ "http://*/*", "https://*/*" ], "js": [ "content.js" ] } ], "content_security_policy": "script-src 'self' 'unsafe-eval'; object-src 'self'" }

ビルドの設定を作成

webpackの設定を行います。

// webpack.config.js const webpack = require('webpack'); const HtmlWebPackPlugin = require('html-webpack-plugin'); const CopyPlugin = require('copy-webpack-plugin'); module.exports = { mode: "production", entry: { popup: './src/popup/index.tsx', background: './src/background/background.ts', content: './src/content/content.tsx', }, output: { path: __dirname + '/dist', }, module: { rules: [ { test: /\.tsx?$/, loader: 'ts-loader', }, { test: /\.html$/, use: [ { loader: 'html-loader', options: { minimize: true }, }, ], }, ], }, resolve: { extensions: [ '.ts', '.js', '.tsx', '.jsx' ] }, plugins: [ new HtmlWebPackPlugin({ template: './public/index.html', filename: './index.html', chunks: ['popup'] // ここはentryの値を入れる }), new CopyPlugin({ patterns: [ { from: './public/manifest.json', to: 'manifest.json' } ] }), ], }

ビルドの自動化

package.jsonに以下を追記。ファイルの変更を検知して自動でビルドしてもらいましょう。。。

// package.json // webpack modeのデフォルトはproducion, configはあれば読んでくれるので省略 { ... "scripts": { "build": "webpack --mode production --config webpack.config.js", "build-watch": "webpack --watch", ... }, ... }

$ npm run build-watchでファイルの変更を監視して、変更があり次第ビルドしてくれます。

ついでにlintと自動修正

ついでにESLintを導入してみます。

まずはパッケージのダウンロード。

$ npm install --save-dev eslint-config-airbnb eslint-plugin-import eslint-plugin-react eslint-plugin-jsx-a11y eslint $ npm install --save-dev gulp gulp-eslint

eslint

JavaScriptのコードからフォーマットの違いとかを発見して通知してくれる。

eslint-config-airbnb

airbnbの設定を適用するのに必要

eslint-plugin-import

eslintでimport/exportに対応する

eslint-plugin-react

eslintでreactに対応する

eslint-plugin-jsx-a11y

jsxの静的解析に対応する

gulp

gulpを使うのに必要

gulp-eslint

gulpでeslintを使うために必要

設定ファイルの追加。項目は適宜変更してください。

// .eslintrc.js module.exports = { "env": { "browser": true, "es6": true }, "extends": "airbnb", "parserOptions": { "sourceType": "module" }, "rules": { "indent": [ "error", 2 ], "linebreak-style": [ "error", "unix" ], "quotes": [ "error", "single" ], "semi": [ "error", "always" ] } };

gulpでタスクにして、自動化します。

// gulpfile.js const gulp = require("gulp"); const eslint = require("gulp-eslint"); const applyLintPaths = [ "src/**/*.{js,jsx,ts,tsx}", "gulpfile.js" ]; /** * lint */ gulp.task("lint", function () { return ( gulp.src(applyLintPaths) .pipe(eslint({ fix: true })) .pipe(eslint.format()) .pipe(gulp.dest((file) => file.base)) // overwrite fixed file .pipe(eslint.failAfterError()) ); }); gulp.task("lint-watch", function () { return ( gulp.watch(applyLintPaths, gulp.task("lint")) ); });

package.jsonの書き換え。

// package.json { ... "scripts": { ... "lint": "gulp lint", "lint-watch": "gulp lint-watch", ... }, }

$ npm run lint or $ npm run lint-watchでlintできます。

ついでにsass対応

ソース内で、import '**.scss'が使えるようにします。

まずはパッケージのダウンロード。

$ npm install --save-dev style-loader css-loader sass-loader sass

style-loader

DOMにCSSを注入するのに必要

css-loader

importやrequireで読み込まれるcssファイル解決に必要

sass

sassをJavaScriptで実装したもの

sass-loader

sass, scssファイルを読み込んで、cssにコンパイルするのに必要

ビルドの設定をいじる。

// webpack.config.js module.exports = { module: { rules: [ ... { test: /\.s[ac]ss$/i, use: [ // Creates `style` nodes from JS strings "style-loader", // Translates CSS into CommonJS "css-loader", // Compiles Sass to CSS "sass-loader", ], }, ], }, };

contentをいじったり、sass書��たり。

// src/content/content.tsx ... import './content.scss'; ...

// src/content/content.scss $bgcolor: black; $color: white; button { background-color: $bgcolor; color: $color; }

tsでのエイリアスの貼り方

tsconfig.jsonの変更

{ "compilerOptions": { ... "baseUrl": "./", "paths": { "@/*": ["src/*"] } }, ... }

webpack.config.jsの変更

const path = require('path'); module.exports = { ... resolve: { alias: { '@': path.resolve(__dirname, 'src/') }, extensions: [ '.ts', '.js', '.tsx', '.jsx' ] }, ... }

viteを使っている場合はvite.config.tsを変更

import { defineConfig } from 'vite' import react from '@vitejs/plugin-react' // https://vitejs.dev/config/ export default defineConfig({ ... plugins: [react()], resolve: { alias: { "@/": `${__dirname}/src/`, } } })

lintも設定

$ npm install --save-dev eslint-import-resolver-webpack

.eslintrc.jsの変更

module.exports= { ... "settings": { "react": { "version": "detect" }, "import/resolver": { "webpack": { "config": path.join(__dirname, "webpack.config.js") } } } }

参考

Create a custom work item control with Azure DevOps extension SDK

The Azure DevOps Web Extension SD or Azure DevOps Extension SDK is a client SDK for developing extensions for Azure DevOps. In this example I will show you how to make a custom work item control using this SDK.

Here is an example of a small project with a custom work item.

Prerequisites

We will need the following before we get started with building our extension:

NodeJS

Setting up the project

We start setting up the project by running the following NPM command in your project directory:

npm init

You can configure these settings as you wish. These can be found in package.json.

we need to install the following packages a dependencies:

npm i azure-devops-extension-api azure-devops-extension-sdk azure-devops-ui react react-dom

as well as the following dev dependencies:

npm i @types/react @types/react-dom copy-webpack-plugin cross-env css-loader loader-utils node-sass rimraf sass sass-loader style-loader tfx-cli ts-loader typescript webpack webpack-cli --save-dev

Now your package.json should look something like, the packager versions might be different:

{ "name": "testextension", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "author": "", "license": "ISC", "dependencies": { "azure-devops-extension-api": "^1.158.0", "azure-devops-extension-sdk": "^2.0.11", "azure-devops-ui": "^2.167.49", "react": "^16.14.0", "react-dom": "^16.14.0" }, "devDependencies": { "@types/react": "^18.0.25", "@types/react-dom": "^18.0.8", "copy-webpack-plugin": "^11.0.0", "cross-env": "^7.0.3", "css-loader": "^6.7.1", "loader-utils": "^3.2.0", "node-sass": "^7.0.3", "rimraf": "^3.0.2", "sass": "^1.56.0", "sass-loader": "^13.1.0", "style-loader": "^3.3.1", "tfx-cli": "^0.12.0", "ts-loader": "^9.4.1", "typescript": "^4.8.4", "webpack": "^5.74.0", "webpack-cli": "^4.10.0" } }

Create two directories inside your root directory: src and static. in this example we won’t be adding anything to the static folder, but it is meant for, for example image files that your project uses. For now, you can add a file named .gitkeep instead.

Next up is configuring TypeScript. Create tsconfig.json in your root folder and put the following inside it:

{ "compilerOptions": { "charset": "utf8", "experimentalDecorators": true, "module": "amd", "moduleResolution": "node", "noImplicitAny": true, "noImplicitThis": true, "strict": true, "target": "es5", "rootDir": "src/", "outDir": "dist/", "jsx": "react", "lib": [ "es5", "es6", "dom", "es2015.promise", "es2019" ], "types": [ "react", "node" ], "esModuleInterop": true } }

Now we configure Webpack. Create webpack.config.js in your root folder and put the following inside it:

const path = require("path"); const fs = require("fs"); const CopyWebpackPlugin = require("copy-webpack-plugin");

const entries = {};

const ComponentsDir = path.join(__dirname, "src/Components"); fs.readdirSync(ComponentsDir).filter(dir => { if (fs.statSync(path.join(ComponentsDir, dir)).isDirectory()) { entries[dir] = "./" + path.relative(process.cwd(), path.join(ComponentsDir, dir, dir)); } });

module.exports = { entry: entries, output: { filename: "[name]/[name].js" }, resolve: { extensions: [".ts", ".tsx", ".js"], alias: { "azure-devops-extension-sdk": path.resolve("node_modules/azure-devops-extension-sdk") }, }, stats: { warnings: false }, module: { rules: [ { test: /\.tsx?$/, loader: "ts-loader" }, { test: /\.s[ac]ss?$/, use: ["style-loader", "css-loader", "azure-devops-ui/buildScripts/css-variables-loader", "sass-loader"] }, { test: /\.css?$/, use: ["style-loader", "css-loader"], }, { test: /\.woff?$/, type: 'asset/inline' }, { test: /\.html?$/, loader: "file-loader" } ] }, plugins: [ new CopyWebpackPlugin({ patterns: [ { from: "**/*.html", context: "src/Components" } ] }) ] };

The last configuration we need to make is specifically for Azure DevOps extensions. Again, in the root directory, create a new file, this time it’s called azure-devops-extension.json:

{ "manifestVersion": 1.0, "id": "textextension", "publisher": "your Visual Studio Marketplace publisher here", "version": "0.0.1", "public": false, "name": "testextension", "description": "custom control", "categories": [ "Azure Boards" ], "targets": [ { "id": "Microsoft.VisualStudio.Services" } ], "icons": { "default": "logo.png" }, "content": { "details": { "path": "README.md" } }, "scopes": [ "vso.work" ], "files": [ { "path": "static", "addressable": true }, { "path": "dist", "addressable": true } ] }

Now, you might notice how this configuration file needs two files: README.md and logo.png. You can add these files in your root folder.

Making the custom control

inside the src directory, create a new React component, let’s name the file Common.tsx.

import "azure-devops-ui/Core/override.css" import "es6-promise/auto" import * as React from "react" import * as ReactDOM from "react-dom" import "./Common.scss"

export function showRootComponent(component: React.ReactElement<any>) { ReactDOM.render(component, document.getElementById("root")) }

It is important we import "azure-devops-ui/Core/override.css", so that we can use standardized UI styling.

This component is more or less our root component, which renders our other components inside a HTML element with id “root��.

Also create a Common.scss file. All we’re going to add to this is:

body { margin: 0; padding: 0; }

Inside the src folder, let’s make another directory named Components and inside that folder create another one named TestExtensionComponent.

src │ Common.scss │ Common.tsx │ └───Components └───TestExtensionComponent

Inside the TestExtensionComponent folder, we’re going to add a few files. First off is TestExtensionComponent.html, this will be our html that will contain the component(s) of your custom control.

<!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <body> <div id="root"></div> <script type="text/javascript" src="TestExtensionComponent.js" charset="utf-8"></script> </body> </html>

Next is TestExtensionComponent.scss.

@import "node_modules/azure-devops-ui/Core/_platformCommon.scss";

This will import the Azure DevOps styling.

Now add TestExtensionComponent.json, this is our component configuration file. Let’s add an input to the configuration, let’s call it SampleInput

{ "contributions": [ { "id": "TestExtensonComponent", "type": "ms.vss-work-web.work-item-form-control", "targets": [ "ms.vss-work-web.work-item-form" ], "properties": { "name": "cusom control", "uri": "dist/TestExtensonComponent/TestExtensonComponent.html", "inputs": [ { "id": "SampleInput", "name": "sample input", "description": "sample input", "validation": { "dataType": "String", "isRequired": true } } ] } } ], "scopes": [ "vso.work" ] }

Next is TestExtensionComponent.tsx

import React, { Component } from 'react' import * as SDK from "azure-devops-extension-sdk" import { IWorkItemFormService, WorkItemTrackingServiceIds, WorkItemOptions } from "azure-devops-extension-api/WorkItemTracking"

import "./TestExtensionComponent.scss"

import { showRootComponent } from "../../Common"

class TestExtensionComponent extends Component<{}, {}> {

constructor(props: {}) { super(props) }

public componentDidMount() { SDK.init({}) }

public render(): JSX.Element { return ( <></> ) } }

export default RESTRequestButton showRootComponent(<RESTRequestButton />)

The component doesn’t do much for now. What is important is the SDK.Init() inside the ComponentDidMount(). This makes sure we can use the Azure DevOps Extension SDK in our component.

So, what if we want to get input data? For example, our SampleInput we configured in the json. We can use the Azure DevOps Extension SDK for that.

To the constructor add:

this.state = { displayText: "default text", }

and to the Component after the extends keyword:

class TestExtensionComponent extends Component<{}, { displayText : string }>

SDK.Init() inside ComponentDidMount() is a Promise so, we can use then-chaining to set our state values there.

public componentDidMount() { SDK.init({}) .then( () => { this.setState({ displayText: SDK.getConfiguration().witInputs["SampleInput"] }) }) }

Now in our render() we can display the input data

public render(): JSX.Element { return ( <>{this.state.displayText}</> ) }

You might also want the data of the current Work Item, we can do this with the IWorkItemFormService interface.

const workItemFormService = await SDK.getService<IWorkItemFormService>( WorkItemTrackingServiceIds.WorkItemFormService )

Then we can use this to get specific fields

const fieldValues : Promise<{[fieldName: string]: Object}> = workItemFormService.getFieldValues(fields, options)

fields here is an array of strings containing key names of the work item, for example: System.Title, System.AssignedTo or Custom.HasPineapple

options is a class that implements WorkItemOptions, which can be done quite easily like

class Options implements WorkItemOptions { returnOriginalValue: boolean = true }

Now, the variablefieldValues is a Promise, so you can use then-chaining to get the data.

Say, we want to display the title of the work item instead on the SampleInput, we could modify our code to look like this:

public componentDidMount() { SDK.init({}) .then( () => { const workItemFormService = await SDK.getService<IWorkItemFormService>( WorkItemTrackingServiceIds.WorkItemFormService ) const fieldValues : Promise<{[fieldName: string]: Object}> = workItemFormService.getFieldValues(fields, options)

fieldValues.then( data =>

this.setState({ displayText: data["System.Title"] }) ) }) }

TypeScript / type

Hoy les traigo como generar un alias para los tipos de datos, espero les sea de utilidad!

Bienvenidos sean a este post, hoy veremos otra mecanica para aplicar a los tipos. En typescript se incorpora el concepto de alias para tipos,, si hacemos un paralelismo lo podemos comparar con typedef de C++ donde a tipos de datos lo podemos asignar a un alias, para resumirlo por citar un ejemplo, primero veamos como es su sintaxis: type nombre_alias = tipo_dato; Siempre va precedido por la…

TOP 10 NEW FEATURES & UPDATES OF ANGULAR 12

Angular 12 is now added in the latest addition to Google's popular TypeScript. Released in May of 2021, the framework comes with many extras like bug fixes, performance improvement, and features. As a learner of the Angular framework, staying updated with all the latest additions is vital.

Srishti Campus is the best Angular training center.

Hop into the ten latest additions to Angular 12 to keep abreast of the add-ons

Towards Ivy

The Angular team had consistently worked on the objective of integrating the Angular ecosystem on Ivy. The current libraries will be working on the Ivy app by depreciating the old View Engine. The library authors will now be working on moving towards Ivy to keep up.

To have a comprehensive understanding, Srishti Campus is the best training center.

Uncertain Protractor

There are speculations about not involving Protractor in the upcoming projects by the team. Currently, the feedback is under trial in the RFC. However, the community is working on exploring popular third party solutions available in Angular CLI. At present, the community of developers are working with Cypress, TestCafe, and Webdrive for elective solutions.

Nullish Coelsing

For writing a cleaner code, the nullish coalescing operator has been in the league for some time. Updating the Angular applications now helps simplify the process of conditional statements.

Here's how the new update makes coding easier:

TypeScript 4.2

Several updates have been made for Angular 12, including improvements in type alias, abstract classes, tuple types, and operators. No important variables or information will appear randomly by improving the in-operator. Infact, the improved version returns valid handles and suitable types, thereby lessening the errors and repetition.

New Styling

Along with the several changes made in the styling, the support for inline SaaS in the style field and component decorators is significant. Moreover, a brand new SaaS model has been adopted by Angular Material and CDK.

Tailwind CSS's support is also made by this version of Angular, given its development and popularity in the Tailwind community.

A Strict Module

Enabling the strict mode by default in CLI has added another feature. With this, catching bugs and better maintenance becomes more manageable. Application examinations are also made way quicker than before with the update.

New Dev Tools

Access to Angular Dev Tools was enabled after the release of Angular 12. After every preview, the embedded profiler can now capture the changed detection. It can be later monitored to figure out the delay detection cycle.

A New Learning Experience

With the aim of improving the learning experience of developers, Angular 12 has also brought some crucial changes for an improved learning experience. This can be noticed in the Angular 12 documentation with a content projection guide.

Along with it, the contributors guide will also aid the developers in elevating the basic understanding of a project documentation. A few useful tips and guides on debugging have also been shared.

A change from the i18n framework

The message-id designs were used in the i18n framework. However, this thought could be put on hold. Angular 12 has added a new and improved intuitive ID format that decreases the cost of invalidation and retranslation. The belated design is comparatively complex yet natural.

Inbuilt Production Build

Presently, the ng build command comes with improved results. However, in the new Angular 12, the production build will come by default

Alpine.js: A Minimal Framework for Composing JS Behavior in Your Markup — We only gave Alpine a brief link when it first dropped but with new versions coming out thick and fast, we think it’s well worth a look. Billed as “like Tailwind for JavaScript”, Alpine lets you keep the HTML you know and love and just pepper it with JavaScript as and where appropriate.

Hotkey 1.4: Trigger an Action on an Element When a 'Hotkey' is Pressed — Use Hotkey, set the data-hotkey attribute on your elements, and you get keyboard shortcuts. GitHub built and uses it (look for the data-hotkey attributes on their pages).

GitHub

web-worker: Consistent Web Workers for the Browser and Node — In Node it works as a web-compatible Worker implementation atop worker_threads. In the browser it’s an alias for Worker.
