dprint - JS Formatter

JS formatter for dprint Wasm plugins.

Setup

Deno:

1deno add @dprint/formatter

Node.js:

1npm i @dprint/formatter

Use

1import { createStreaming, GlobalConfiguration } from "@dprint/formatter";
2
3const globalConfig: GlobalConfiguration = {
4  indentWidth: 2,
5  lineWidth: 80,
6};
7const tsFormatter = await createStreaming(
8  // check https://plugins.dprint.dev/ for latest plugin versions
9  fetch("https://plugins.dprint.dev/typescript-0.57.0.wasm"),
10);
11
12tsFormatter.setConfig(globalConfig, {
13  semiColons: "asi",
14});
15
16// outputs: "const t = 5\n"
17console.log(tsFormatter.formatText("file.ts", "const   t    = 5;"));

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

1import { createFromBuffer } from "@dprint/formatter";
2// You may have to use `getBuffer` on plugins that haven't updated yet.
3// See the plugins README.md for details.
4import { getPath } from "@dprint/json";
5import * as fs from "node:fs";
6
7const buffer = fs.readFileSync(getPath());
8const formatter = createFromBuffer(buffer);
9
10console.log(formatter.formatText("test.json", "{test: 5}"));
