1. Create a Lambda function: called `get-groups`
const data = [ {name: 'angular', id: 1}, {name: 'react', id: 2}, {name: 'vue', id: 3} ]; exports.handler = async (event) => { const response = { statusCode: 200, headers: { 'Access-Control-Allow-Origin': '*' }, body: JSON.stringify({items: data}), }; return response; };
To prevent CORS problems, we enables CORS headers as well.
2. Create an API Gateway
- For REST API
- Build a New Rest API
- Actions -> Create Resource, this is used as endpoint, let's named `groups`
- Action -> Create Method, `GET`
- Actiona -> Deploy
3. After deployed, it generate a URL you can used for testing in POSTMAN
GET: https://<id>.execute-api.us-east-1.amazonaws.com/dev/groups
