slim's Issues

Overview

This project is the implementation of the minimal production loader RFC. The repository is for the loader part.

The loader needs to be able to:

• Execute a bundle of JavaScript.
• Progressively load JavaScript using some syntax (of our choosing) (maybe like steal.import).
• Execute bundles loaded in any order (using script async).
• Allow for some type of runtime plugins. This is mostly (and perhaps only) for CSS, so that's the target.

As code size is extremely important here, some guidelines for what we want to achieve:

• The loader should not be any larger than the one provided by webpack.
• The loader could possibly be broken up by feature set to minimize size. For example there might be a loader.js that does the main loader stuff, and then a progressive.js which adds the ability to support steal.import, and then a plugin.js which adds the ability for plugins to exist. The build process would determine which features are needed and combine loader.js, progressive.js, and plugin.js. Whether we do this depends on the code size.

Plan

As this is a rather large project this issue needs to be broken up into several tasks.

Loader

Build

This change will happen within steal-tools. We will need some optional way to enable the minimal loader. Probably with an option.

stealTools.build({}, {
  minimalLoader: true
});

The challenge here is to figure out how to detect which features we do not support and to throw appropriate error messages. We cannot support:

• Use of runtime configuration
• Use of steal-specific modules like @loader or @steal. We can probably just hardcode these for now.
