Rollup Plugin Redirectory

OverlayFS-like resolver for Rollup.

Usage

yarn add -D @anireact/rollup-plugin-rediretory

npm install --save-dev @anireact/rollup-plugin-rediretory

import rediretory from '@anireact/rollup-plugin-rediretory';

export default {
    plugins: [
        rediretory({
            root: process.cwd(),
            mappings: {
                // When a file in `<root>/transpiled` imports something,
                // and resolution fails, fall back to `<root>/src`:
                transpiled: 'src',

                // When a file in `<root>/src` imports something,
                // and resolution fails, fall back to `<root>/generated`:
                src: 'generated',
            },
        }),
    ],
};

Options

• root (default: process.cwd()) — the project root directory.
• mappings — a record of key-value directory mappings; both keys and values are relative to root.

Why

Let’s consider a project, that has:

1. JS and CSS files in /src.
2. TS files from /src, transpiled with tsc to /tmp.

We don’t want to copy everything from /src to /tmp, so if /src/main.mts transpiled to /tmp/main.mts imports ./styles.css, the resolution will fail, because ./styles.css cannot be resolved in /tmp. To solve this, we could just tell Rollup to check /src when resolving files from /tmp — if the original resolution fails.
