I'm migrating from NPM to Yarn, and I want to run scripts in parallel such as:
npm-run-all --parallel script1 script2 script3
What is its equivalent in Yarn?
What I found as its equivalent is to run each separately:
yarn run script1 && yarn run script2 && yarn run script3
but I can't run scripts in parallel.
how to use multiple scripts & in parallel?

“yarn run commands in parallel” Code Answer's js, but you can use it to run any commands.
The official npm run-script command cannot run multiple scripts, so if we want to run multiple scripts, it's redundant a bit. Let's shorten it by glob-like patterns. Cross platform. We sometimes use & to run multiple command in parallel, but cmd.exe ( npm run-script uses it by default) does not support the & .
After running npm i concurrently to install it, you can then set up your NPM start script to run multiple commands just by separating each individual command with quotes. And once again, you should be off to the races.
There is a difference between using & and &&. Using & will run scripts in parallel, using && will run scripts one after the other.
package.json:
{
"parallel": "yarn script1 & yarn script2",
"serial": "yarn script1 && yarn script2",
"script1": "... some script here",
"script2": "... some there script here"
}
From what I read on documentation of npm-run-all, you can just keep using it, and, as long as you run the script with yarn it will use YARN to run scripts in parallel.
Here is the original quote from https://github.com/mysticatea/npm-run-all
Yarn Compatibility
If a script is invoked with Yarn, npm-run-all will correctly use Yarn to execute the plan's child scripts.
