Documentation

Plugin Install

To install the HTTP Plugin, add http to Leverage.

import { add } from "@leverage/core";
import { http } from "@leverage/plugin-http";

add(http);

Events

The HTTP Plugin can be configured using events. The server can also be told to start listening.

import { add, emit } from "@leverage/core";
import { http } from "@leverage/plugin-http";

add(http);

// Configure the Fastify instance
await emit("http:configure", {
    /*
     * All configuration options are passed directly to the Fastify server.
     * https://www.fastify.io/docs/latest/Server/
     */
    ignoreTrailingSlash: true,
});

// Tell the server to start listening on a port
await signal("http:listen", {
    port: 8080,
});

Components

A HTTP component holds configuration for a route.

import { useHTTP } from "@leverage/plugin-http";

export const init = () => {
    useHTTP({
        /*
         * All configuration options are passed directly to `fastify.route()`.
         * https://www.fastify.io/docs/latest/Routes/
         */
        path: "/hello-world",
        method: "GET",
    });
};

// Any Fastify handlers/callbacks are also passed to `fastify.route()`.
export const handler = (request, reply) => {
    /* ... */
};
export const preHandler = (request, reply) => {
    /* ... */
};
export const onSend = (request, reply) => {
    /* ... */
};

Additionally, connect-style middleware can be used by exporting a middleware function.

import { useHTTP } from "@leverage/plugin-http";
import cors from "cors";

export const init = () => {
    useHTTP();
};

export const middleware = cors();

Hooks

useHTTP

The useHTTP hook can be used to configure an HTTP component.

import { useHTTP } from "@leverage/plugin-http";

export const init = () => {
    useHTTP({
        /*
         * All configuration options are passed directly to `fastify.route()`.
         * https://www.fastify.io/docs/latest/Routes/
         */
        path: "/hello-world",
        method: "GET",
    });
};

import { useHTTP } from "@leverage/plugin-http";

export const init = () => {
    /*
     * When called without a config, the component is still configured for use
     *  with the HTTP plugin. This is useful when used for middleware with the
     *  `useMiddleware` hook.
     */
    useHTTP();
};
