> 最近阅读了一下[ant-design-vue](https://github.com/vueComponent/ant-design-vue.git)源码，学习到了很多关于项目自动化相关的知识和技巧, 本篇就是针对[prettier api](https://prettier.io/docs/en/api.html)的文件格式化命令脚本. ## 脚本代码 哈哈,ant-design-vue作者还在头部标明是copy to https://github.com/facebook/react/blob/master/scripts/prettier/index.js ```js /** * copy to https://github.com/facebook/react/blob/master/scripts/prettier/index.js * prettier api doc https://prettier.io/docs/en/api.html *----------*****-------------- * prettier all js and all ts. *----------*****-------------- */ const glob = require('glob'); const prettier = require('prettier'); const fs = require('fs'); const prettierConfigPath = require.resolve('../.prettierrc'); let didError = false; let files = []; const ignoreFiles = [ '**/node_modules/**', 'package.json', 'build/**', 'es/**', 'lib/**', 'dist/**', '**/**.snap', '**/**.map', '**/components/style/color/**', '**/dist/**', '_site/**', ]; // get all ts files const tsFiles = glob.sync('**/*.ts*', { ignore: ignoreFiles, }); files = files.concat(tsFiles); // get all js files const jsFiles = glob.sync('**/*.js*', { ignore: ignoreFiles, }); files = files.concat(jsFiles); // get all less files const lessFiles = glob.sync('**/*.less', { ignore: ignoreFiles, }); files = files.concat(lessFiles); if (!files.length) { return; } files.forEach(file => { const options = prettier.resolveConfig.sync(file, { config: prettierConfigPath, }); const fileInfo = prettier.getFileInfo.sync(file); if (fileInfo.ignored) { return; } try { const input = fs.readFileSync(file, 'utf8'); const withParserOptions = { ...options, parser: fileInfo.inferredParser, }; const output = prettier.format(input, withParserOptions); if (output !== input) { fs.writeFileSync(file, output, 'utf8'); // eslint-disable-next-line no-console console.log(`\x1b[34m ${file} is prettier`); } } catch (e) { didError = true; } }); if (didError) { process.exit(1); } // eslint-disable-next-line no-console console.log('\x1b[32m prettier success!'); ``` ## 命令 执行 `prettier -c --write **/*` ``` // package.json { ... "script": { ... "prettier": "prettier -c --write **/*" } } ```
