Serverless REST API with DynamoDB and offline support

This example demonstrates how to run a service locally, using the serverless-offline plugin. It provides a REST API to manage Todos stored in a DynamoDB, similar to the aws-node-rest-api-with-dynamodb example. A local DynamoDB instance is provided by the serverless-dynamodb-local plugin.

Use-case

Test your service locally, without having to deploy it first.

Setup

Note: Your node version must be v15.4 or below, or POST requests will not work with serverless offline.

npm i -g serverless@2.72.3
npm install
serverless dynamodb install (or to use a persistent docker dynamodb instead, open a new terminal: cd ./dynamodb && docker-compose up -d)
serverless offline start
serverless dynamodb migrate (this imports schema)

Run service offline

serverless offline start

Usage

You can create, retrieve, update, or delete todos with the following commands:

Create a Todo

curl -X POST -H "Content-Type:application/json" http://localhost:3000/dev/todos --data '{ "text": "Learn Serverless" }'

Example Result:

{"text":"Learn Serverless","id":"ee6490d0-aa11e6-9ede-afdfa051af86","createdAt":1479138570824,"checked":false,"updatedAt":1479138570824}%

List all Todos

curl -H "Content-Type:application/json" http://localhost:3000/dev/todos

Example output:

[{"text":"Deploy my first service","id":"ac90feaa11e6-9ede-afdfa051af86","checked":true,"updatedAt":1479139961304},{"text":"Learn Serverless","id":"206793aa11e6-9ede-afdfa051af86","createdAt":1479139943241,"checked":false,"updatedAt":1479139943241}]%

Get one Todo

# Replace the <id> part with a real id from your todos table
curl -H "Content-Type:application/json" http://localhost:3000/dev/todos/<id>

Example Result:

{"text":"Learn Serverless","id":"ee6490d0-aa11e6-9ede-afdfa051af86","createdAt":1479138570824,"checked":false,"updatedAt":1479138570824}%

Update a Todo

# Replace the <id> part with a real id from your todos table
curl -X PUT -H "Content-Type:application/json" http://localhost:3000/dev/todos/<id> --data '{ "text": "Learn Serverless", "checked": true }'

Example Result:

{"text":"Learn Serverless","id":"ee6490d0-aa11e6-9ede-afdfa051af86","createdAt":1479138570824,"checked":true,"updatedAt":1479138570824}%
