Browser · Prettier

Run Prettier in the browser with the standalone.js UMD bundle shipped in the NPM package (starting in version 1.13). The new UMD bundle only formats the code and has no support for config files, ignore files, CLI usage, or automatic loading of plugins.

`prettier.format(code, options)`

Unlike the format function from the main API, this function does not load plugins automatically, so a plugins property is required if you want to load plugins. Additionally, the parsers included in the Prettier package won't be loaded automatically, so you need to load them before using them.

See Usage below for examples.

Usage

Global

<script src="https://unpkg.com/prettier@1.13.0/standalone.js"></script>
<script src="https://unpkg.com/prettier@1.13.0/parser-graphql.js"></script>
<script type="text/javascript">
prettier.format("query { }", { parser: "graphql", plugins: prettierPlugins });
</script>

AMD

define([
  "https://unpkg.com/prettier@1.13.0/standalone.js",
  "https://unpkg.com/prettier@1.13.0/parser-graphql.js"
], (prettier, ...plugins) => {
  prettier.format("query { }", { parser: "graphql", plugins });
});

CommonJS

const prettier = require("prettier/standalone");
const plugins = [require("prettier/parser-graphql")];
prettier.format("query { }", { parser: "graphql", plugins });

This syntax doesn't necessarily work in the browser, but it can be used when bundling the code with browserify, Rollup, webpack, or another bundler.

Worker

importScripts("https://unpkg.com/prettier@1.13.0/standalone.js");
importScripts("https://unpkg.com/prettier@1.13.0/parser-graphql.js");
prettier.format("query { }", { parser: "graphql", plugins: prettierPlugins });
