Visual Studio Code（VS Code）是微软为 Linux、Windows 和 macOS 创建的跨平台代码编辑器。遗憾的是，微软版本的 VS Code 是在 Microsoft Software License 下发布的，这不是一个开源的许可证。然而，它的源代码是开源的，在 MIT 许可证下由 VSCodium 项目发布。
VSCodium 和 VS Code一样，支持扩展、内嵌式 Git 控制、GitHub 集成、语法高亮、调试、智能代码补完、代码片段等。换句话说，对于大多数用户来说，使用 VS Code 和 VSCodium 没有什么区别，而且后者是完全开源的！
什么是 VS Code 扩展？
扩展 可以让你为 VS Code 或 VSCodium 添加功能。你可以在 GUI 中或从终端安装扩展。
// The module 'vscode' contains the VSCodium extensibility API // Import the module and reference it with the alias vscode in your code below import * as vscode from "vscode"; const fs = require("fs"); const path = require("path");
// this method is called when your extension is activated // your extension is activated the very first time the command is executed export function activate(context: vscode.ExtensionContext) {
// Use the console to output diagnostic information (console.log) and errors (console.error) // This line of code will only be executed once when your extension is activated console.log('Congratulations, your extension "initdockerapp" is now active!'); // The command has been defined in the package.json file // Now provide the implementation of the command with registerCommand // The commandId parameter must match the command field in package.json let disposable = vscode.commands.registerCommand('initdockerapp.initialize', () => { // The code you place here will be executed every time your command is executed
let fileContent =` FROM node:alpine WORKDIR /usr/src/app
COPY package.json . RUN npm install COPY . . EXPOSE 3000 CMD ["npm", "start"] `; fs.writeFile(path.join(vscode.workspace.rootPath, "Dockerfile"), fileContent, (err:any) => { if (err) { return vscode.window.showErrorMessage("Failed to initialize docker file!"); } vscode.window.showInformationMessage("Dockerfile has been created!"); }); });
context.subscriptions.push(disposable); }
// this method is called when your extension is deactivated export function deactivate() {}
