lazyload-es2015-webpack-test
Test usage of LazyLoad as es2015 module in a WebPack build.
Installation
Install LazyLoad with the command
npm install vanilla-lazyload
Or install a specific version with
npm install vanilla-lazyload@{{version}}
Usage
The best solution which works out of the box is to use the ES6 module syntax (aka ESM), and import LazyLoad like the following:
import LazyLoad from "vanilla-lazyload";
const lazyLoadOptions = {/* your options here */};
const pageLazyLoad = new LazyLoad(lazyLoadOptions);
See lazyload-init.js for an example, or go to LazyLoad's readme file for documentation.
If using the ESM syntax isn't possible for you and you wish to continue using the CJS require
syntax, read usage as CommonJS module below.
Build
Configure the build
script in your package.json
like the following:
{
"scripts": {
"build": "webpack"
}
}
Then, in your terminal, run:
npm run build
Result
To see the result, open the dist/index.html
file.
That's it!
Usage as CommonJS module
In case you want to import LazyLoad using the require
directive, you must configure WebPack to load the scripts from the package.json's main
fields instead. More info.
So edit your webpack.config.js
file and add or edit the resolve.mainFields
setting to ["main", "browser", "module"]
like follows:
module.exports = {
// other configuration fields here
resolve: {
mainFields: ["main", "browser", "module"]
}
};
This tells WebPack to resolve your require
s to the packages main
field, which must contain contains the UMD version of the installed modules. More info.
For an example usage, see the commonJS
branch on this very repo.
