Set the PRETTIER_DEBUG environment variable to a non-empty value if you want Prettier to rethrow these errors. For example, a plugin that has nodes with embedded JavaScript might have the following embed method: function embed(path, options) { const node = path.node; if (node.type === "javascript") { return async (textToDoc) => { return [ "<script>", hardline, await textToDoc(node.javaScriptCode, { parser: "babel" }), hardline, "</script>", ]; }; } } If the --embedded-language-formatting option is set to off, the embedding step is entirely skipped, embed isn’t called, and all nodes are printed with the print method.

January 28, 2018 - In one parse the output is pretty and you can use the regular babel CLI --watch mode.

June 23, 2025 - Since Prettier 3.6, *.frag files except *.start.frag, *.end.frag, start.frag, and end.frag are no longer treated as JavaScript files. If you have JavaScript files with .frag that do not match the patterns mentioned above, you can config with overrides. export default { overrides: { files: "**/*.frag", options: { parser: "babel", }, }, }; Previously, languages API for custom plugins only supported inferring parser based on the file basename or extension.

Latest version: 1.0.5, last published: 2 years ago. Start using @standard-configs/prettier-plugin-babel in your project by running `npm i @standard-configs/prettier-plugin-babel`. There are 4 other projects in the npm registry using @standard-configs/prettier-plugin-babel.

Babel plugin to use prettier for transformed code output - goto-bus-stop/babel-plugin-generator-prettier

Babel's configuration merging is relatively straightforward. Options will overwrite existing options when they are present and their value is not undefined. There are, however, a few special cases: For assumptions, parserOpts and generatorOpts, objects are merged, rather than replaced. For plugins and presets, they are replaced based on the identity of the plugin/preset object/function itself combined with the name of the entry.

June 12, 2023 - I don't understand why its throwing an error in general, as I do have the plugin added to the standalone. Also, I am using the Babel parser and its throwing an error for estree. ... import * as prettier from "prettier/standalone" import parserBabel from "prettier/plugins/babel"; prettier.format("foo ( )", { parser: "babel", plugins: [parserBabel] });

October 15, 2023 - [error] src/index.ts: SyntaxError: This experimental syntax requires enabling one of the following parser plugin(s): "importAttributes", "importAssertions". (3:37) I tried adding a babel.config.json file containing the following:

You can also switch to the flow parser instead of the default babel for .js files:

It’s been removed in v3.0.0 as its functionality was a subset of what the Plugin API did. If you used it, please check the example below on how to migrate. ❌ Custom parser API (removed): import { format } from "prettier"; format("lodash ( )", { parser(text, { babel }) { const ast = babel(text); ast.program.body[0].expression.callee.name = "_"; return ast; }, }); // -> "_();\n" ✔️ Plugin API: import { format } from "prettier"; import * as prettierPluginBabel from "prettier/plugins/babel"; const myCustomPlugin = { parsers: { "my-custom-parser": { async parse(text) { const ast = await prettierPluginBabel.parsers.babel.parse(text); ast.program.body[0].expression.callee.name = "_"; return ast; }, astFormat: "estree", }, }, }; await format("lodash ( )", { parser: "my-custom-parser", plugins: [myCustomPlugin], }); // -> "_();\n" note ·

"babel-ts" (similar to "typescript" but uses Babel and its TypeScript plugin) First available in v2.0.0

April 14, 2025 - In this post, we’ve walked through how to set up ESLint and Prettier in a React project created without CRA (using Webpack and Babel).

As I already use Babel to compile our source code I would like to create a Babel plugin which transforms my code. Sadly Babel alone is not good in preserving whitespace and formatting. Thankfully I use Prettier for that and because Prettier uses Babel internally I can create a Babel visitor to transform my source code.
