Hooks

To extend functionality and to react on certain events, luna-js introduces a hook system. You have multiple of hooks available. To register a hook, create a file inside one of the directories you defined inside the hooks section of your luna.config.js.

The hook can either be synchronous or asynchronous.

Example of the SERVER_STARTED hook:

import {HOOKS} from "@webtides/luna-js/src/framework/hooks/definitions";

const name = HOOKS.SERVER_STARTED;
export { name };

export default () => {
    console.log("Express server has started");
};

Example of the REQUEST_RECEIVED hook:

import {HOOKS} from "@webtides/luna-js/src/framework/hooks/definitions";

const name = HOOKS.REQUEST_RECEIVED;
export { name };

export default async ({ request, response }) => {
    console.log("Request received.");
};

In some cases, a hook can receive additional parameters from luna-js.
