Preface

Nowadays, the front-end development has changed from the traditional manual introduction of cdn resources to an engineering development system, the introduction of external resources are through npm installation dependencies, import dependencies for use. How to develop a npm dependency package is not difficult. This article will show how to develop a simple npm dependency package, develop and upload the npm platform, you can install and use in the project.

Register for npm

If you want to develop the npm dependency package to be downloaded and used by others, you need to upload the final development project to the npm platform for management. First go to the npm platform to register an account, the registration process is very simple.

Create a project

Create a new folder javascript-test (the name can be customized)

In the javascript-test terminal console, execute npm init, fill in as prompted, and finally generate a package.json project description file

{

"name": "javascript-test"

"version": "1.0.0"

"description": "npm-test"

"main": "index.js"

"scripts": {

"test": "echo\" Error: no test specified\ "& exit 1"

}

"keywords": [

"npm-test"

]

"author": "Hunter"

"license": "ISC"

}

Create an index.js file, the project entry file, in the javascript-test root directory, corresponding to the main configuration in the package.json file

Function init () {

Console.log ('Hello Worldwide')

}

Export {init}

The javascript-test terminal console executes npm login, and according to the prompts, enter the account password to log in to npm

After logging in successfully, execute npm publish to publish (Note: the name configuration in package.json file is the name of npm dependent package, which cannot be duplicated with the name of dependent package on npm platform, otherwise publishing fails)

After the release is successful, you can see your dependency package on the npm platform.
