Static Assets

Farm treat modules that is not treated as code as Static Assets, for example, images like png/svg/etc, text files like txt/xlsx/etc. This document describes how Farm deal with these assets.

url

Import a image：

import rocketUrl from './assets/rocket.svg'; // return the url of this image

export function Main() {
  return <img src={rocketUrl} /> // using the url
}

Default to use url method when import a image. When using url methods to import a image, the image will be emitted to the output dir directly, and the image module itself will be compiled to a js module like:

export default '/rocket.<content hash>.svg'

using compilation.output.assetFilename to config your asset name。

inline

Using query ?inline to tell Farm that you want to inline your assets，then the assets will be transformed to base64，for example：

// importer
import logo from './assets/logo.png?inline'; // logo is a base 64 str

// the image module will be compiled to:
export default 'data:image/png,base64,xxxxx==';

raw

Using query ?raw to tell Farm that you want to read the raw string of the assets, for example

// import 
import logo from './assets/license.txt?raw'; // return the content string of the assets

// the txt file will be compiled to:
export default 'MIT xxxx';

Configuring Assets

• Using compilation.output.assetFileName to control the production file name
• using compilation.assets.include to treat more kind of files as asset modules.

import { defineConfig } from '@farmfe/core';

export default defineConfig({
  compilation: {
    output: {
      assetFilename: 'assets/[resourceName].[hash].[ext]', // [] is a placeholder, Farm currently only these three kind of placeholders
    },
    assets: {
      include: ['txt'] // extra static asset extension
    }
  }
});
