dprint - JS Formatter


JS formatter for dprint Wasm plugins.

Setup

Deno:

``sh
deno add npm:@dprint/formatter
`

Node.js:

`sh
npm i @dprint/formatter
`

Use

The context API allows you to manage multiple plugins with shared configuration and automatic plugin selection based on file type:

`ts
import { createContext } from "@dprint/formatter";
import * as json from "@dprint/json";
import * as markdown from "@dprint/markdown";
import * as typescript from "@dprint/typescript";
import fs from "node:fs";

const context = createContext({
// global config
indentWidth: 2,
lineWidth: 80,
});

// note: some plugins might have a getBuffer() export instead
context.addPlugin(fs.readFileSync(typescript.getPath()), {
semiColons: "asi",
});
context.addPlugin(fs.readFileSync(json.getPath()));
context.addPlugin(fs.readFileSync(markdown.getPath()));

console.log(context.formatText({
filePath: "config.json",
fileText: "{\"a\":1}",
}));

console.log(context.formatText({
filePath: "app.ts",
fileText: "const x=1",
}));
``

The context also handles host formatting automatically, so embedded code blocks (like JSON in Markdown) will be formatted by the appropriate plugin.

Note: In the future I will ensure plugins are published to JSR as well.
