@podium/fastify-layout

Fastify plugin for @podium/layout.

Module for building @podium/layout servers with fastify. For writing layouts, please see the Podium documentation.

Installation

npm install @podium/fastify-layout

Simple usage

Build a simple layout server including a single podlet:

import FastifyLayout from '@podium/fastify-layout';
import Layout from '@podium/layout';
import fastify from 'fastify';

const app = fastify({ logger: true });

const layout = new Layout({
    pathname: '/',
    logger: console,
    name: 'layout',
});

const podlet = layout.client.register({
    name: 'myPodlet',
    uri: 'http://localhost:7100/manifest.json',
});

app.register(FastifyLayout, layout);

app.get(layout.pathname(), async (request, reply) => {
    const incoming = reply.app.podium;
    const result = await podlet.fetch(incoming);
    return reply.podiumSend(result.content);
});

const start = async () => {
    try {
        await app.listen({ port: 7000 });
        app.log.info(`server listening on ${app.server.address().port}`);
    } catch (err) {
        app.log.error(err);
        process.exit(1);
    }
};
start();

Register plugin

The plugin is registered by passing an instance of this plugin to the fastify server .register() method together with an instance of the @podium/layout class.

app.register(FastifyLayout, layout);

Request params

On each request @podium/layout will run a set of operations on the request and create an [incoming] object. The [incoming] object is stored at reply.app.podium which is accessible inside request handlers.

app.get('/', async (request, reply) => {
    console.log(reply.app.podium.context);
    [ ... ]
});

Its possible to pass request bound parameters to @podium/context parsers by setting an object at reply.app.params.

Example: To pass a value to the @podium/context locale parser it should be set on reply.app.params by a extension executed previously of this extension.

reply.podiumSend(fragment)

This method will wrap the given fragment in a default document template before dispatching.

See document template for further information.
