I want to run a script during every build that generates some assets, how can I achieve it?

Hi @frail lance. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

To generate assets during every build in Astro, you can use the astro:build:setup hook. This hook allows you to run custom code at the beginning of the build process. Here's how you can achieve this:

  1. Create an integration file (e.g., generate-assets.js) in your project.

  2. In this file, export a default function that returns an object with the astro:build:setup hook.

  3. Inside the hook, you can run your asset generation script.

Here's an example of how your integration file might look:

export default function generateAssets() {
  return {
    name: 'generate-assets',
    hooks: {
      'astro:build:setup': async () => {
        // Run your asset generation script here
        await generateYourAssets();
      }
    }
  };
}

async function generateYourAssets() {
  // Your asset generation logic goes here
  console.log('Generating assets...');
  // For example: await generateImages();
}

After creating this integration, you need to add it to your Astro configuration file (astro.config.mjs):

import generateAssets from './generate-assets.js';

export default defineConfig({
  integrations: [generateAssets()]
});

This setup will ensure that your asset generation script runs at the beginning of every build process.

For more information on Astro's integration API and hooks, you can refer to the Astro Integration API documentation (https://docs.astro.build/en/reference/integrations-reference/#astrobuildsetup).

Remember that the assets generated during the build process should be output to a location that will be included in your final build, such as the public/ directory or a directory specified in your build configuration.
