Configuring npm Scripts
npm scripts are defined in the package.json
file under the scripts
field. You can define custom scripts and configure them according to your project requirements. Each script is associated with a command or a series of commands to be executed when the script is run.
Here’s an example of how scripts are defined in the package.json
file:
{
"name": "my-project",
"version": "1.0.0",
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"lint": "eslint ."
},
"dependencies": {
"react": "^17.0.2",
"react-scripts": "4.0.3"
},
"devDependencies": {
"eslint": "^7.32.0"
}
}
In this example:
- The
start
,build
,test
, andlint
scripts are defined with their respective commands. react-scripts
andeslint
are listed as dependencies, which are used by the scripts.
