🖼️ IPX

> [!NOTE] > This is the active branch for IPX v2. Check out ipx/v1 for v1 docs.

High performance, secure and easy-to-use image optimizer powered by sharp and svgo.

Used by Nuxt Image and Netlify and open to everyone!

Using CLI

You can use ipx command to start server.

Using npx:

npx ipx serve --dir ./

Usin bun

bun x npx ipx serve --dir ./

The default serve directory is the current working directory.

Programatic API

You can use IPX as a middleware or directly use IPX interface.

import { createIPX, ipxFSStorage, ipxHttpStorage } from "ipx";

const ipx = createIPX({
  storage: ipxFSStorage({ dir: "./public" }),
  httpStorage: ipxHttpStorage({ domains: ["picsum.photos"] }),
});

Example: Using with unjs/h3:

import { listen } from "listhen";
import { createApp, toNodeListener } from "h3";
import {
  createIPX,
  ipxFSStorage,
  ipxHttpStorage,
  createIPXH3Handler,
} from "ipx";

const ipx = createIPX({
  storage: ipxFSStorage({ dir: "./public" }),
  httpStorage: ipxHttpStorage({ domains: ["picsum.photos"] }),
});

const app = createApp().use("/", createIPXH3Handler(ipx));

listen(toNodeListener(app));

Example: Using express:

import { listen } from "listhen";
import express from "express";
import {
  createIPX,
  ipxFSStorage,
  ipxHttpStorage,
  createIPXNodeServer,
} from "ipx";

const ipx = createIPX({
  storage: ipxFSStorage({ dir: "./public" }),
  httpStorage: ipxHttpStorage({ domains: ["picsum.photos"] }),
});

const app = express().use("/", createIPXNodeServer(ipx));

listen(app);

URL Examples

Get original image:

/_/static/buffalo.png

Change format to webp and keep other things same as source:

/f_webp/static/buffalo.png

Keep original format (png) and set width to 200:

/w_200/static/buffalo.png

Resize to 200x200px using embed method and change format to webp:

/embed,f_webp,s_200x200/static/buffalo.png
