Need help to find correct configuration for monorepo project.

Hi @pmowrer, @alisd23,

I am unable to find out correct configuration to publish(to artifactory) only those components where file is modified.

Below is the command executed after I change any src file of component: git add . git cz (commitzen)

Below is the command I execute for testing, building and publishing component:

npm install
node_modules/.bin/ng lint component1 --force=true --format=json > component1_lint-out.json
node_modules/.bin/ng test component1 --code-coverage --browsers ChromeHeadless
node_modules/.bin/ng lint component2 --force=true --format=json > component2_lint-out.json
node_modules/.bin/ng test component2 --code-coverage --browsers ChromeHeadless
node_modules/.bin/ng lint component3 --force=true --format=json > component3_lint-out.json
node_modules/.bin/ng test component3 --code-coverage --browsers ChromeHeadless
node_modules/.bin/ng build component1
node_modules/.bin/ng build component2
node_modules/.bin/ng build component3
npx semantic-release -e semantic-release-monorepo

here only component1 gets published to JFrog Artifactory

Here I wanted to avoid building each component, and instead of that have config in root package.json to achieve that.

I have following monorepo project structure:

master-project(Project root)

|_-> apps
|_-> e2e
|_-> libs
|_-> projects
       |_-> component1 -> package.json
       |_-> component2 -> package.json
       |_-> component3 -> package.json
|_-> package.json

component1 package.json content:

{
  "name": "component1",
  "version": "0.0.1-semantically-released",
  "peerDependencies": {
    "@angular/common": "^6.0.0-rc.0 || ^6.0.0",
    "@angular/core": "^6.0.0-rc.0 || ^6.0.0"
  }
}

I know “pkgRoot”: “./dist/component1/” is the one which is causing only component1 to publish. But if I try “pkgRoot”: [“./dist/component1/”, “./dist/component2/”, “./dist/component3/”] it is throwing error.

Please suggest on how to achieve:

1. Publish only those component where actully file got changed.
2. Version bump (minor or major or patch) only for specific component where file got changed.

Help wanted!

Thanks @pmowrer for your input. And yes integrating lerna did help. Right now I am testing it, and results are on positive side.

Hi @swapniljv!

Please suggest on how to achieve:

1. Publish only those component where actully file got changed.
2. Version bump (minor or major or patch) only for specific component where file got changed.

Both points listed is exactly why semantic-release-monorepo exists!

I would suggest using lerna to run semantic-release-monorepo across each package in your monorepro. See README for more details.
