The withFaust helper function is used to merge your next.config.js config with necessary Faust.js configuration.

Usage

To use withFaust, create a next.config.js file in your project root with the following content:

next.config.js

const { withFaust } = require('@faustjs/next');

/**
 * @type {import('next').NextConfig}
 **/
module.exports = withFaust();
Code language: JavaScript (javascript)

If you already have a next.config.js file, you can use the first argument of withFaust to merge in your existing config.

Take the following example, where we have a custom next.config.js handling a rewrite:

next.config.js

const { withFaust } = require('@faustjs/next');

const nextConfig = {
  async rewrites() {
    return [
      {
        source: '/about',
        destination: '/',
      },
    ];
  },
};

/**
 * @type {import('next').NextConfig}
 **/
module.exports = withFaust(nextConfig);
Code language: JavaScript (javascript)

Additional Options

withFaust also accepts a second argument for withFaustConfig. withFaustConfig represented as a TypeScript interface looks like:

interface WithFaustConfig {
  // Where preview links will be redirected to.
  previewDestination?: string;
}
Code language: JavaScript (javascript)

For example, if you wanted to change the default preview destination from /preview to /previews, you can do so by passing the following to withFaust:

next.config.js

const { withFaust } = require('@faustjs/next');

const nextConfig = {};

const withFaustConfig = {
  previewDestination: '/previews',
};

/**
 * @type {import('next').NextConfig}
 **/
module.exports = withFaust(nextConfig, withFaustConfig);Code language: JavaScript (javascript)

NOTE
If you change the previewDestination path, do not forget to create an associated page with the same name for that destination. Otherwise the framework will redirect to a non existing page and it will show a 404 response.
