Crawling

Where can I find a man who has forgotten words so I can have a word with him?

Hi folks!

When you removing a variable, or manipulate in any way with it, for example

import {readFile} from 'fs/promises';
import {writeFile} from 'fs/promises';

log(readFile, writeFile);

Will be converted with merge-duplicate-imports to:

import {readFile, writeFile} from 'fs/promises';

log(readFile, writeFile);

But! When you have declare-undefined-variables enabled: you in trouble! And most likely see error message like this:

TypeError: Cannot read properties of undefined (reading 'buildError')

This is the way Babel tries to tell you that there is names collision, and code contains a couple variables with the same name.

The thing is merge-duplicate-imports doesn't crawl the tree with help of:

path.scope.getProgramParent().crawl();

It only removes old nodes, and adds a new one.

This is a thing that adds variables to bindings object, so other plugins can determine whether they declared or not.

But worry not! This behaviour was fixed in even more! You don't ever need to think about was AST crawled after your plugin made fixes or not. From now it's crawled on every fix 🎉 !

That's all for today! Have a nice weekend!
