transaction serverless

ThinBlock's Transaction API is built using AWS Lambda and Serverless. It depends on NodeJS server v8.10.

Installation

We use yarn to install the packages. Do

 yarn install

Deploy

In order to deploy offline, simply run

serverless offline start

In order to deploy the you endpoint simply run

serverless deploy

The expected result should be similar to:

Serverless: Packaging service…
Serverless: Uploading CloudFormation file to S3…
Serverless: Uploading service .zip file to S3…
Serverless: Updating Stack…
Serverless: Checking Stack update progress…
...........................
Serverless: Stack update finished…

Service Information
service: serverless-simple-http-endpoint
stage: dev
region: us-east-1
api keys:
  None
endpoints:
  GET - https://2e16njizla.execute-api.us-east-1.amazonaws.com/dev/transaction
functions:
  serverless-simple-http-endpoint-dev-transaction: arn:aws:lambda:us-east-1:488110005556:function:serverless-simple-http-endpoint-dev-transaction

Usage

You can now invoke the Lambda directly and even see the resulting log via

serverless invoke --function transaction --log

or as send an HTTP request directly to the endpoint using a tool like curl

curl https://XXXXXXX.execute-api.us-east-1.amazonaws.com/dev/transaction
