Add API Endpoints to a Website in Launch

Launch allows you to write Cloud Functions to create API endpoints.

This step-by-step guide lets you add API endpoints to a website in Launch.

1. Contentstack account
2. Access to Launch for your organization

Follow the steps given below to write a Cloud Function that can be used to add API endpoints to a website in Launch.

1. Create a folder named /functions under a source folder in your project’s root folder.
2. Create a JavaScript file to code your functions and then save the file to the /functions folder.

   Example:

   // functions/users.js
   
   
   export default function handler(request, response) {
   
       const users = [
   
         {name: "Jack", age: "25"},
   
         {name: "Rick", age: "28"},
   
         {name: "Jane", age: "34"},
   
       ];
   
       response.status(200).send(users);
   
     }
   

3. Zip the source folder that contains the /functions folder.
4. Deploy your project in Launch using one of the following methods:
   1. Import from a Git Repository
   2. Upload a file
   After successful deployment, you will see the Cloud Functions displayed in the log:The function endpoint is determined by its file path relative to /functions. The function runs when you visit the path: /users.
5. Click the icon next to the URL in the Domains section to open the deployed website.In this example, the URL of the API endpoint will be https://sample-test-api.devsampleapp.com/users.
6. On sending a request to the API Endpoint, you will see the following response:
    [
   
       {
   
         "name": "Jack",
   
         "age": "25"
   
       },
   
       {
   
         "name": "Rick",
   
         "age": "28"
   
       },
   
       {
   
         "name": "Jane",
   
         "age": "34"
   
       }
   
    ]
