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.
