    Webpack module-nomodule plugin

    npm version

    Installation

    npm install --save-dev webpack-module-nomodule-plugin

    or

    yarn add -D webpack-module-nomodule-plugin

    Why

    This automates the generation of module-nomodule scripts.

    This project relies on html-webpack-plugin.

    module-nomodule explained.

    How to use

    1. Create separate build steps for your modern and legacy builds in your webpack config.
    2. Each build step should include at least one use of the html-webpack-plugin with the inject: 'body' option set.
    3. Include this plugin with the name of the configuration in the constructor (e.g. new WebpackModuleNomodulePlugin('legacy'); or new WebpackModuleNomodulePlugin('modern');)

    The rest will be handled for you!

    Output modes

    The second argument to WebpackModuleNomodulePlugin allows you to specify an output mode.

    At this point there are two:

    • efficient (default)
    • minimal

    These are exported as an object containing OUTPUT_MODES.

    Efficient

    Ensures IE11 and some Edge versions won't double download the contents of your scripts. This adds some more size to your html file and defers the loading of scripts.

    This will look something like this:

    efficient mode output

    What happens in this picture?

    • We declare the modern javascript files as modulepreload to shave a bit off the load/parse time of these
    • We dynamically inject the entry-modules with the bigger script to avoid injecting needlessly

    Minimal

    Makes the most minimal output possible, this will be downloaded twice on older Edge and IE11.

    This will look something like this:

    minimal mode output

    The script in the middle between type="module" and nomodule is meant for safari 11 compat.

    nomodule will load for browsers who don't support module and the other way around, the problem with this approach is we'll be downloading both bundles on certain Edge versions and IE11.

    This example uses multiple techniques to guarantee the best size, like using native-url in modern browsers, ...
