Cost/benefit of NodeJS GraphQL implementation

NodeJS implementation GraphQL

simple graphql-modules, apollo server setup with modules utilizing GraphQL

• https://github.com/maapteh/graphql-golang
• https://github.com/maapteh/graphql-nodejs

1. yarn
2. yarn dev

http://localhost:4000/graphql

Setup

We are testing three NodeJS versions

• src/apollo.ts Apollo with simple typeDefs and resolvers merged, with graphql-jit executor
• src/index.ts Apollo setup with the graphql-modules, with graphql-jit executor
• src/helix.ts Helix standard

Profiling

Two profile dist apps:

1. yarn profile:flamegraph 0x flamegraph
2. yarn profile:clinic clinic doctor

Example for Static query, not calling any async resolvers

hey: now put some load on it for 10 seconds

hey -n 200 -c 80 -cpus 1 -z 10s -m POST --disable-keepalive -H "client-name: readme" -H "client-version: 1.0.0" -H "X-Authorization: foo" -H "Content-Type: application/json" -H 'client-name: readme' -H 'client-version: 1.0.0' -d '{ "query": "{ version }" }' http://localhost:4000/graphql

Curl

Test if application works from commandline:

curl \
  -X POST \
  -H "Content-Type: application/json" \
  -H 'client-name: readme' \
  -H 'client-version: 1.0.0' \
  -H "X-Authorization: FOO.BAR" \
  --data '{ "query": "{ version }" }' \
  http://localhost:4000/graphql
