Serverless graphql endpoint for PostgresSQL database using AWS, serverless and postgraphql

Official lambda implementation from the postgraphql-creators: https://github.com/graphile/postgraphile-lambda-example

How to use my implementation:

Setup

💾 Install Serverless

👯 Clone the repo

git clone https://github.com/rentrop/serverless-postgraphql
cd serverless-postgraphql

💾 Install

npm install

🚀 Rebuild and Deploy

npm run rebuild-and-deploy

☕ Coffeetime: AWS takes ~10min to setup the Postgres DB

  • From the result of the serverless deployment take the pgEndpoint and insert it in:
    • package.json-file in the config of PGCON (line 7)
    • serverless.yml-file in the environment-variable named PGCON (line 21)

🚀 Rebuild and Deploy Again

npm run rebuild-and-deploy

You are all set now. You can now query the resulting endpoint as you wish via POST and GET.

One example to authenticate a user would be:

mutation {
  authenticate(input: {email: "spowell0@noaa.gov", password: "iFbWWlc"}) {
    jwtToken
  }
}

You can try this by entering the following in your browser:

your-url/dev/graphql?query=mutation%20%7B%0Aauthenticate%28input%3A%20%7Bemail%3A%20%22spowell0%40noaa.gov%22%2C%20password%3A%20%22iFbWWlc%22%7D%29%20%7B%0AjwtToken%0A%7D%0A%7D

For most other queries you need to be authorised. Authorization in postgraphql is done via the jwtToken. Set this in your following requests as Authorization header:

Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhIjoxLCJiIjoyLCJjIjozfQ.hxhGCCCmGV9nT1slief1WgEsOsfdnlVizNrODxfh1M8
