Add support for import { platform } from "process"

[mindplay-dk]

🙋 feature request

I'm trying to bundle ansi-colors for the web, which references process.platform.

Tthis is currently not supported, which means a Node.JS import statement is currently left behind in web-targeted output:

import{platform as e}from"process";

🤔 Expected Behavior

The bundler should perform static analysis on process.platform properties and resolve expressions at compile-time - similar to how process.env gets resolved, perhaps even reusing the same code.

🔦 Context

#7904 was recently resolved and received an enhancement to better support ansi-colors, but didn't get all the way there.

💻 Example

See this project for reference.

This should replace process.platform with undefined in browsers, because it's not declared here

This should replace process.platform with undefined in browsers

It probably should statically resolve process.platform and compile it away entirely, if possible - same way process.env expressions get evaluated at compile-time, pruning conditional branches that can't/shouldn't be executed in the browser.

That's what I meant. Replacing the expression process.platform statically with an undefined literal at build time.
