dprint - JS Formatter

JS formatter for dprint Wasm plugins.

Setup

Deno:

deno add @dprint/formatter

Node.js:

npm i @dprint/formatter

Use

import { createStreaming, GlobalConfiguration } from "@dprint/formatter";

const globalConfig: GlobalConfiguration = {
  indentWidth: 2,
  lineWidth: 80,
};
const tsFormatter = await createStreaming(
  // check https://plugins.dprint.dev/ for latest plugin versions
  fetch("https://plugins.dprint.dev/typescript-0.57.0.wasm"),
);

tsFormatter.setConfig(globalConfig, {
  semiColons: "asi",
});

// outputs: "const t = 5\n"
console.log(tsFormatter.formatText({
  filePath: "file.ts",
  fileText: "const   t    = 5;",
}));

Using with plugins on npm (ex. @dprint/json):

import { createFromBuffer } from "@dprint/formatter";
// You may have to use `getBuffer` on plugins that haven't updated yet.
// See the plugins README.md for details.
import { getPath } from "@dprint/json";
import * as fs from "node:fs";

const buffer = fs.readFileSync(getPath());
const formatter = createFromBuffer(buffer);

console.log(formatter.formatText({
  filePath: "test.json",
  fileText: "{test: 5}",
}));
