Prettier Apex Server in docker image

Run apex parsing server in docker to speed up apex formatting with prettier. Needed to be able to run prettier apex parser in server mode on CI machines, which reduces apex formatting file time from around 1 second to 20 ms.

How to use

Developer machine

docker run -it -p 2117:2117 ziemniakoss/prettier-apex-server:latest

And after that whenever you run prettier, add these flags:

--apex-standalone-parser built-in

Bitbucket

Make sure that you have these dependencies and scripts in package.json

"devDependencies": {
	"prettier": "^2.8.1",
	"prettier-plugin-apex": "Your selected version",
	"wait-on": "^6.0.1"
},
"scripts": {
	"preprettier-check": "wait-on http://127.0.0.1:2117/api/ast/",
	"prettier-check": "prettier  --apex-standalone-parser built-in --list-different ."
}

After that, add prettier apex server definition to bitbucket-pipelines.yml

image: atlassian/default-image:3
definitions:
  services:
    prettier-apex:
      image: ziemniakoss/prettier-apex-server:latest # or your selected version
pipelines:
  default:
    - step:
        name: "Validate with prettier"
        services:
          - docker
          - prettier-apex
        caches:
          - docker
        script:
          - npm ci
          - npm run prettier-check

Github

Just like in bitbucket, this can be implemented using service containers
