Prerequisites

Before you begin, ensure you have the following installed:

Installation

  1. Clone the repository:

    git clone https://github.com/marco0antonio0/About-express-netlify
    cd About-express-netlify
    
  2. Install dependencies:

    npm install
    

Configuration

  1. Create netlify.toml file:

    [functions]
        external_node_modules = ["express"]
        node_bundler = "esbuild"
    
    [[redirects]]
        force = true
        from = "/api/*"
        status = 200
        to = "/.netlify/functions/api/:splat"
    
    [build]
        command = "echo Building Functions"
    
  2. Create netlify/functions/api.js file:

        import express, { Router } from "express";
        import serverless from "serverless-http";
    
        const api = express();
    
        const router = Router();
        router.get("/hello", (req, res) => res.send("Hello World!"));
    
        api.use("/api/", router);
    
        export const handler = serverless(api);
    
    
  3. Ensure your package.json includes the necessary dependencies:

        {
        "name": "example_project",
        "version": "1.0.0",
        "main": "index.js",
        "scripts": {
        "test": "echo \"Error: no test specified\" && exit 1"
        },
        "keywords": [],
        "author": "",
        "license": "ISC",
        "description": "",
        "dependencies": {
            "@netlify/functions": "^2.7.0",
            "@types/express": "^4.17.21",
            "express": "^4.19.2",
            "serverless-http": "^3.2.0"
                }
        }
    

Usage

Once deployed, you can access your Express.js API through the Netlify URL. For example, if your Netlify site is https://yoursite.netlify.app, you can access the API endpoint at:

  https://yoursite.netlify.app/api/hello
Enter fullscreen mode Exit fullscreen mode

This should return Hello World!.
