  • [Javascript] An Introduction to JSPM (JavaScript Package Manager)

    JSPM can handle installed packages, transpiling ES6, and bundling all from the command-line. This video gives a quick overview of install JSPM, installing packages with JSPM, writing a very simple app in ES6 that uses those packages, then bundling up for production.

    Install:

    npm install jspm -g

    You can use jspm to install any package:

    jspm install --save lodash moment

    This will help you to create package.json and you need to select some default options such as transplier: Babel.

    We create index.html, to import system.js and config.js files whcih created by jspm. Then use System.js to import the app.js file.

    <!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title></title>
        <script src="./jspm_packages/system.js"></script>
        <script src="config.js"></script>
        <script>
            System.import('app');
        </script>
    </head>
    <body>
    
    
    </body>
    </html>

    app.js:

    import moment from 'moment';
    import _ from 'lodash';
    
    let date = moment().format();
    
    _.forEach(date, char => console.log(char));

    In the file we can use ES6 already.

    Then when you open the index.html you will see it works.

    RUN:

    jspm bundle-sfx --minify app

    This will create a build.js file,

    Replace html with:

    <!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title></title>
        <script src="build.js"></script>
    </head>
    <body>
    
    
    </body>
    </html>

    Only includes new build.js file, u will see everything still works.
