APPS-7 : Automatically detect package manager and install dependencies on init

[achaaoui-yc]

JIRA Ticket

APPS-7

I could not get this pr to be tested perfectly locally, so to qa it well, we need to follow some steps.

To know the package manager used by the user, I used this env var npm_config_user_agent that all package managers set. to know what each one of them puts in it, we need to:

Steps

• Start a process with a package manager of choice npm, pnpm or yarn, (eg, pnpm init @youcan/create-app)
• Find the pid of the process, (ps aux | grep create-app)
• Inspect its env variables and look for npm_config_user_agent, (ps -Eww | grep <PID> | tr ' ' '\n' | grep npm_config_user_agent)
• Make a note of it's value you might want to use the other package managers too.

QA Steps

• Run

npm_config_user_agent={value_retrieved} {path_to_cloned_repo}/cli/packages/create-app/bin/exec.js

• Follow the steps and see the node_module is installed.

Note

• I am using --no-progress option for npm install , bc it messes up the out put, it might be fixed, but still to figure it out if wanted.
• The Installing dependencies... task seems out of style, to think of a better way to handle unloadable tasks.
