Use path params in serverless framework 1.0

Question

I want to use the path param /customer/{customerId} of a GET request in order to query a customer using AWS Lambda:

functions:

  createCustomer:

    handler: handler.createCustomer

    events:

    - http:

        path: customer

        method: post

  readCustomer:

    handler: handler.readCustomer

    events:

    - http:

        path: customer

        method: get

How do I have to define the path param in order to pass it to my AWS Lambda function using serverless framework 1.0?

Answer 1

In serverless.yml, add this:

readCustomer:

  handler: handler.readCustomer

  events:

    - http:

        path: customer/{customerId}

        method: get

In code, you can access customerId

const customerId = event.pathParameters.customerId;
