| See our website [@babel/generator](https://new.babeljs.io/docs/en/next/babel-generator.html) for more information or the [issues](https://github.com/babel/babel/issues?utf8=%E2%9C%93&q=is%3Aissue+label%3A%22pkg%3A%20generator%22+is%3Aopen) associated with this package. | ||
| ## Install | ||
| Using npm: | ||
| ```sh | ||
| npm install --save-dev @babel/generator | ||
| npm install --save @babel/generator | ||
| ``` | ||
| ## Usage | ||
| or using yarn: | ||
| ```js | ||
| import {parse} from '@babel/parser'; | ||
| import generate from '@babel/generator'; | ||
| const code = 'class Example {}'; | ||
| const ast = parse(code); | ||
| const output = generate(ast, { /* options */ }, code); | ||
| ```sh | ||
| yarn add --save @babel/generator | ||
| ``` | ||
| ## Options | ||
| Options for formatting output: | ||
| name | type | default | description | ||
| -----------------------|----------|-----------------|-------------------------------------------------------------------------- | ||
| auxiliaryCommentBefore | string | | Optional string to add as a block comment at the start of the output file | ||
| auxiliaryCommentAfter | string | | Optional string to add as a block comment at the end of the output file | ||
| shouldPrintComment | function | `opts.comments` | Function that takes a comment (as a string) and returns `true` if the comment should be included in the output. By default, comments are included if `opts.comments` is `true` or if `opts.minifed` is `false` and the comment contains `@preserve` or `@license` | ||
| retainLines | boolean | `false` | Attempt to use the same line numbers in the output code as in the source code (helps preserve stack traces) | ||
| retainFunctionParens | boolean | `false` | Retain parens around function expressions (could be used to change engine parsing behavior) | ||
| comments | boolean | `true` | Should comments be included in output | ||
| compact | boolean or `'auto'` | `opts.minified` | Set to `true` to avoid adding whitespace for formatting | ||
| minified | boolean | `false` | Should the output be minified | ||
| concise | boolean | `false` | Set to `true` to reduce whitespace (but not as much as `opts.compact`) | ||
| filename | string | | Used in warning messages | ||
| jsonCompatibleStrings | boolean | `false` | Set to true to run `jsesc` with "json": true to print "\u00A9" vs. "©"; | ||
| Options for source maps: | ||
| name | type | default | description | ||
| -----------------------|----------|-----------------|-------------------------------------------------------------------------- | ||
| sourceMaps | boolean | `false` | Enable generating source maps | ||
| sourceRoot | string | | A root for all relative URLs in the source map | ||
| sourceFileName | string | | The filename for the source code (i.e. the code in the `code` argument). This will only be used if `code` is a string. | ||
| ## AST from Multiple Sources | ||
| In most cases, Babel does a 1:1 transformation of input-file to output-file. However, | ||
| you may be dealing with AST constructed from multiple sources - JS files, templates, etc. | ||
| If this is the case, and you want the sourcemaps to reflect the correct sources, you'll need | ||
| to pass an object to `generate` as the `code` parameter. Keys | ||
| should be the source filenames, and values should be the source content. | ||
| Here's an example of what that might look like: | ||
| ```js | ||
| import {parse} from '@babel/parser'; | ||
| import generate from '@babel/generator'; | ||
| const a = 'var a = 1;'; | ||
| const b = 'var b = 2;'; | ||
| const astA = parse(a, { sourceFilename: 'a.js' }); | ||
| const astB = parse(b, { sourceFilename: 'b.js' }); | ||
| const ast = { | ||
| type: 'Program', | ||
| body: [].concat(astA.program.body, astB.program.body) | ||
| }; | ||
| const { code, map } = generate(ast, { sourceMaps: true }, { | ||
| 'a.js': a, | ||
| 'b.js': b | ||
| }); | ||
| // Sourcemap will point to both a.js and b.js where appropriate. | ||
| ``` |
