Vercel Serverless Function Template 2024

This repository contains a simple Vercel serverless function template for 2024. It is designed to work out of the box and to be a starting point for deploying serverless functions on Vercel.

Getting Started

Steps

1. Clone the repository:

   git clone https://github.com/techdevwill/Vercel-Serverless-Function-Express.git
   cd Vercel-Serverless-Function-Express

2. Install dependencies:

   npm install

3. Commit to your GitHub repository:

   git add .
   git commit -m "Initial commit"
   git push origin main

4. Deploy on Vercel:

   • Go to Vercel and sign in with your account.
   • Select "New Project" and import your GitHub repository.
   • Follow the prompts to deploy your project.

Usage

Once deployed, you can send requests to your Vercel URL along with the API endpoint. For example:

https://your-vercel-url.vercel.app/api/yourEndPoint

You can change the `yourEndPoint` to anything you would like, and the API call endpoint will update to whatever you called it. For example, if you rename the file to `newEndPoint.js`, your URL will be:

https://your-vercel-url.vercel.app/api/newEndPoint

Adjusting Server Timeout

You can adjust the server timeout for any route by modifying the `vercel.json` file. Here is what the `vercel.json` looks like:

{
    "version": 2,
    "rewrites": [
        {
            "source": "/(.*)",
            "destination": "/api"
        }
    ],
    "functions": {
        "api/yourEndPoint.js": {
            "maxDuration": 60
        }
    }
}

• Replace `yourEndPoint.js` with your endpoint file name.
• Adjust the `maxDuration` parameter to set the timeout (in seconds) for each endpoint.
• Note that Vercel has different max durations for their paid and non-paid plans. Please refer to Vercel's documentation for more details on the limits.

Example cURL Command

Here’s an example of a cURL command to send a request with a parameter `data`:

curl -X POST https://your-vercel-url.vercel.app/api/yourEndPoint \
  -H "Content-Type: application/json" \
  -d '{"data": "Message to express server"}'
