vue脚手架工具(详细步骤)(2)

const ora = require('ora'); // 开始下载 const spinner = ora('正在下载模板...'); spinner.start(); // 下载失败调用 spinner.fail(); // 下载成功调用 spinner.succeed();

然后通过 chalk 来为打印信息加上样式，比如成功信息为绿色，失败信息为红色，这样子会让用户更加容易分辨，同时也让终端的显示更加的好看。

const chalk = require('chalk'); console.log(chalk.green('项目创建成功')); console.log(chalk.red('项目创建失败'));

除了给打印信息加上颜色之外，还可以使用 log-symbols 在信息前面加上 √ 或 × 等的图标

const chalk = require('chalk'); const symbols = require('log-symbols'); console.log(symbols.success, chalk.green('项目创建成功')); console.log(symbols.error, chalk.red('项目创建失败'));

完整示例

// index.js #!/usr/bin/env node // 处理用户输入的命令 const program = require('commander'); // 下载模板 const download = require('download-git-repo'); // 问题交互 const inquirer = require('inquirer'); // node 文件模块 const fs = require('fs'); // 填充信息至文件 const handlebars = require('handlebars'); // 动画效果 const ora = require('ora'); // 字体加颜色 const chalk = require('chalk'); // 显示提示图标 const symbols = require('log-symbols'); // 命令行操作 var shell = require("shelljs"); program.version('1.0.1', '-v, --version') .command('init <name>') .action((name) => { if (!fs.existsSync(name)) { inquirer.prompt([ { name: 'description', message: 'Input the object description' }, { name: 'author', message: 'Input the object author' } ]).then((answers) => { const spinner = ora('Downloading...'); spinner.start(); download('zxpsuper/suporka-parcel-vue', name, (err) => { if (err) { spinner.fail(); console.log(symbols.error, chalk.red(err)); } else { spinner.succeed(); const fileName = `${name}/package.json`; const meta = { name, description: answers.description, author: answers.author } if (fs.existsSync(fileName)) { const content = fs.readFileSync(fileName).toString(); const result = handlebars.compile(content)(meta); fs.writeFileSync(fileName, result); } console.log(symbols.success, chalk.green('The vue object has downloaded successfully!')); inquirer.prompt([ { type: 'confirm', name: 'ifInstall', message: 'Are you want to install dependence now?', default: true } ]).then((answers) => { if (answers.ifInstall) { inquirer.prompt([ { type: 'list', name: 'installWay', message: 'Choose the tool to install', choices: [ 'npm', 'cnpm' ] } ]).then(ans => { if (ans.installWay === 'npm') { let spinner = ora('Installing...'); spinner.start(); // 命令行操作安装依赖 shell.exec("cd " + name + " && npm i", function (err, stdout, stderr) { if (err) { spinner.fail(); console.log(symbols.error, chalk.red(err)); } else { spinner.succeed(); console.log(symbols.success, chalk.green('The object has installed dependence successfully!')); } }); } else { let spinner = ora('Installing...'); spinner.start(); shell.exec("cd " + name + " && cnpm i", function (err, stdout, stderr) { if (err) { spinner.fail(); console.log(symbols.error, chalk.red(err)); } else { spinner.succeed(); console.log(symbols.success, chalk.green('The object has installed dependence successfully!')); } }) } }) } else { console.log(symbols.success, chalk.green('You should install the dependence by yourself!')); } }) } }) }) } else { // 错误提示项目已存在，避免覆盖原有项目 console.log(symbols.error, chalk.red('The object has exist')); } }); program.parse(process.argv);

npm publish发布你的项目即可。
