What is the purpose of concurrent in this code snippet?
"scripts": {
"tsc": "tsc",
"tsc:w": "tsc -w",
"lite": "lite-server",
"start": "Concurrent npm run tsc:w npm run lite"
}
As stated in the official documentation.
The section labeled "scripts" serves as a collection of script commands that are executed at different points throughout your package's lifecycle. Each key corresponds to a specific event, while the associated value is the command to be executed at that particular moment.
Therefore, when you use the start
command, it will concurrently run both npm run tsc:w
and npm run lite
. For more information on scripts and how to utilize the run command, refer to the provided links.
Executing npm run tsc:w
compiles your TypeScript code while also monitoring for any changes.
Running npm run lite
initiates the npm server for your current application.
The "script" attribute is utilized to specify the command that can be executed on the terminal.
Executing npm run start
in the command line will trigger the following concurrently:
You must have the node package called concurrently defined as follows :
"devDependencies": {
"concurrently": "^2.0.0"
}
Add it as dependencies/devDependencies in your package.json file so you can use concurrent as a keyword.
Concurrently enables you to
Execute multiple commands simultaneously
