You can add a package.json file to your package to make it easy for others to manage and install. Packages published to the registry must contain a package.json file.
To create a package.json file with values that you supply, use the npm init command.
On the command line, navigate to the root directory of your package.
cd /path/to/package
Run the following command:
npm init

Customizing the package.json questionnaire
If you expect to create many package.json files, you can customize the questions asked and fields created during the init process so all the package.json files contain a standard set of information.
In your home directory, create a file called .npm-init.js.
To add custom questions, using a text editor, add questions with the prompt function:
module.exports = prompt("what's your favorite flavor of ice cream, buddy?", "I LIKE THEM ALL");
To add custom fields, using a text editor, add desired fields to the .npm-init.js file:
module.exports ={
customField: 'Example custom field',
otherCustomField: 'This example field is really cool'
To create a default package.json using information extracted from the current directory, use the npm init command with the --yes or -y flag. For a list of default values, see "Default values extracted from the current directory".
On the command line, navigate to the root directory of your package.
bugs: information from the current directory, if present
homepage: information from the current directory, if present
Setting config options for the init command
You can set default config options for the init command. For example, to set the default author email, author name, and license, on the command line, run the following commands:
The easiest way to create a package. json file is to run npm init to generate one for you. It will ask you to fill out some fields, and then create a package. json file in the current directory.
To define an NPM script, set its name and write the script under the 'scripts' property of your package.json file: To execute your Script, use the 'npm run <NAME-OF-YOUR-SCRIPT>' command. Some predefined aliases convert to npm run, like npm test or package json npm start, you can use them interchangeably.
Open a text editor and enter data in the following Salesforce Analytics schema format: { "fileFormat" : { }, "objects" : [ { <object_detail>, "fields" : [ { <Field1 details> } { <Field2 details> }…… ] }] }
If you're not publishing your project to the NPM registry or otherwise making it publicly available to others, your package.json is still essential to the development flow. Your project also must include a package. json before any packages can be installed from NPM.
While package. json acts as the project's manifest, detailing dependencies and scripts, package-lock. json ensures consistent and reliable installation of these dependencies across different environments.
Bottom line: Let the package managers do their job for consistent, secure, and collaborative development. Treat package-lock. json as a valuable blueprint, not a playground for manual changes.
To add dependencies and devDependencies to a package.json file from the command line, you can install them in the root directory of your package using the --save-prod flag (also -S ) for dependencies (the default behavior of npm install ) or the --save-dev flag (also -D ) for devDependencies.
The file resides in the root directory of every Node.js package and appears after running the npm init command. The package. json file contains descriptive and functional metadata about a project, such as a name, version, and dependencies.
