IE8 CLI is a Tooling for project Development With IE8 Compability.

It is 2019. The users using IE8 is not that much now. Developling this tool seems not a smart move. But, I need to support ie8 (at work). I need a tool to maintain what I have figured out during development. So, this is the reason why it comes out.

IE8 will be completely abandoned someday. And this tool will be totally useless at that time. But, since it uses latest tools such as typescript and webpack4 (which means the projects generated by the tool doesn't need to change much when you decide not to support ie8), it will helps before that time.

This tool is for creating projects with ie8 compability by using preset boilerplates. It integrates several tools:

  • sanjs (a framework kindof like vue)
  • anujs (A mini React-like framework that is extremely compatible with React16)
  • typescript
  • webpack4

I spent a lot of time figuring out how to use latest webpack tools in ie8 development. With this tool, you can develop with webpack 4.x, which means that all proposals is usable only if you set up corresponding babel plugins.

note: there still are some several unsupport features:

  • getter / setter: the defineProperty is wierd in ie8. Please keep in mind that in ie8 defineProperty can only be used with dom instances during development.

Getting Started


npm install -g ie8-cli
