Alda-graphql-server NPM

Setup

yarn add alda-graphql-server add PRISMA_ENDPOINT to .env file e.g. PRISMA_ENDPOINT=http://52.210.29.65:4466

How to add a GraphQL Query/Mutation

We are using GraphQL-Yoga between the frontend and the Prisma-server. GraphQL-Yoga needs a Schema Definition Language (SDL) and the corresponding resolvers. Therefore to add a query/ mutation we have to:

add query/ mutation to SDL in ./SDL.js
add resolver to ./index.js, make sure that the function returns the values defined in the SDL

Test

In ./test I prepared a node application, which exposes the graphql-server and the playground at port 4001. To start the offline serverless test server execute:

cd ./test && yarn start Then open a browser at http://localhost:4001 to make tests in the playground. Note: The GraphQLServerLambda from graphql-yoga does not support the playground at the moment (I could not get it running, even though I still export it). (10.02.2018)

Publish

yarn publish enter new version number and npm credentials. Remember to update alda-backup repository.

AWS Lightsail

start 1024MB RAM, Ubuntu 16.04 instance
install docker and docker-compose
git clone https://github.com/aldabot/alda-graphql-server
cd ./alda-graphql-server/docker
sudo docker-compose up
attach a fixed IP to the AWS Lightsail instance
open port 3306 (MySQL) and 4466 (Prisma) in the AWS Lightsail Network menu Now we have to deploy the schema from our local computer (not from the AWS Lightsail instance)
in the same repository go to cd ./database
change the prisma endpoint to http://{AWSLightsailStaticIp}:4466
prisma deploy
