rollup-plugin-static-import

Rollup plugin for copying imported files without modifying. It's basically a copy plugin with the added functionality of marking imported assets as external.

This is mostly useful when you want to let bundler of application using your library handle some files. SVG icons and SCSS files can be a good example for this.

Also, this mostly makes sense using together with preserveModules option of rollup. If not, all your imports will end up in one file and it will not be tree-shakable by the application bundler (Not 100% sure on this, haven't tested extensively). In that case, you might as well use something like rollup-plugin-scss where all your scss is compiled into one file.

Usage

// rollup.config.js
import staticImport from 'rollup-plugin-static-import'
// ...
  preserveModules: true,
  plugins: [
    //...
    staticImport({ include: ['src/**/*.scss', 'src/**/*.svg']})
  ]
// ...

With this configuration, this plugin will

• Mark scss and svg imports as external, therefore those imports will stay in output bundle as it is.
• Copy all scss and svg files matching globs in include param.
• It will also watch these files and copy them on change if rollup is started in watch mode.

With this output, you can let the application bundler handle scss and svg files.

Parameters

projectRoot (default: process.cwd())

This will be used to create absolute paths out of include, exclude and baseDir parameters. Mostly, rollup is run in project root folder, so default value of process.cwd() works fine and you do not have to think about this at all. But for some reason, if you are running rollup command from a different folder than project root, you should set this to an absolute path pointing to root folder of project (where package.json is located). If you use absolute paths for all other parameters, this parameter will not have any effect.

include* and exclude (default: [])

include and exclude are parameters that are used in almost every rollup plugin and functions in the same way. For this plugin, include is a required parameter.

baseDir (default: 'src')

Base directory that will be used to determine path of copied files. For example src/styles/main.scss with baseDir: 'src' will be copied to <outputDir>/styles/main.scss.
