Right now backend project have several ways of reducing the dependencies (both dependencies and version numbers) and plugins needed to set up a new project. 

One way is using the new Fat Jar feature combined with Target Platforms. This allows them to specify all liferay dependencies with just one line, like:

compileOnly group: "com.liferay.portal", name: "release.portal.api"

For devDependencies, they also add all gradle plugins by applying them with one combined plugin

The goal is achieving something similar: simplifying the way of setting dependencies (and ideally devDependencies too) for external developers.

There are several ways we can achieve, either faking it with the bundler or really adding all the dependencies but the idea is to do it in the simpler way for us.

The PR that caused this conversation is this one and Greg proposed a PoC after it.

This feature has customers and global services in mind, it should not be designed to be used internally.

Test Scenarios:

Requirement	Test Scenarios	Covered by frontend/backend Unit Test?	Test Priority (business impact)	Chrome Pass/Fail
cli tool is intended for non-ootb portal projects. Meaning js projects created from cli/scratch/workspace/template/etc	Given `@liferay/cli` is used via npx When run 'npx @liferay/cli new my-react-project-test' Then a module is created with all necessary js dependencies for the given target platform (ie: *-7.4-GA1)	no	5-critical
	Given `@liferay/cli` is used via npx When run 'npx @liferay/cli new my-react-project-test' And When input different than '7.4' version of platform (ie: *-7.3) Then a module is created with all necessary js dependencies for the given target platform	no	4-major
allow developers to only have a single dependency for their JS project and scope it to a single release of dxp	Given a sample-project index.js/App.js referencing several known dependencies And Given package.json file under dependency only lists "@liferay/portal-7.4-ga1": "^1.0.0" And Given package.json contains a build script with `liferay build` When run `npm build` Then the project is built with all known 7.4 GA1 js dependencies listed in the package.json file And Then only the minimum necessary dependencies are defined by Liferay AMDLoader	no	5-critical

 

Exploratory testing to consider:

Exploratory: explore any other command options with the cli tool `liferay new *`	no	3-medium
