Jets translates your routes.rb file into API Gateway resources, and connects them to your Lambda functions:


Jets.application.routes.draw do
  get  "posts", to: "posts#index"
  get  "posts/new", to: "posts#new"
  get  "posts/:id", to: "posts#show"
  post "posts", to: "posts#create"
  get  "posts/:id/edit", to: "posts#edit"
  put  "posts", to: "posts#update"
  delete  "posts", to: "posts#destroy"

  resources :comments # expands to the RESTful routes above

  any "posts/hot", to: "posts#hot" # GET, POST, PUT, etc request all work

You can check your routes in the API Gateway console:

Note: In Jets v5, only the minimal APIGW Methods are created. APIGW essentially acts like a proxy to the Jets routing engine which is more flexible.

You can get your API Gateway endpoints from the API Gateway console, and test them with curl or postman. Example:

$ curl -s "" | jq .
  "hello": "world",
  "action": "index"

Production Deployment

Important: If you are deploying a production service, it is strongly recommended to use a Custom Domain. Jets computes and figures out whether or not it needs to replace the REST API as part of deployment. When the REST API is replaced, the API Endpoint will be different. By using Custom Domain, you’ll be able to keep the same endpoint.
