Export defaults from node-resolve plugin

• Rollup Plugin Name: node-resolve
• Rollup Plugin Version: 7.1.1

Feature Use Case

I want to be able to add .ts and .tsx extensions when using TypeScript but I have to manually repeat default values which adds up unnecessary manual work. If the defaults were exported, I could reuse them easily.

This would function similarly to const { defaults } = require('jest-config').

I can create a PR if you want.

Feature Proposal

Add export keyword to

plugins/packages/node-resolve/src/index.js

Line 20 in cabe710

const defaults = {

Thanks for the issue. Please expand on your use case further, I don't quite understand what you're trying to do. More code would definitely help.

Sorry if I wasn't clear enough. For node-resolve plugin to see TypeScript files, it needs to be configured to allow .ts and .tsx extensions. If I just set extensions: ['.ts', '.tsx'] it obviously won't work because it will override default extensions.

I could copy and paste defaults and add my custom extensions but I feel like this could be improved if those defaults were exported for me to reuse them.

You can see the example here: https://github.com/kentcdodds/kcd-scripts/pull/131/files#diff-a1cfe028f2f056e2d30db017481d4ad0R146-R150

Thanks for explaining the use case further. Would it be more useful to expose defaults, or do a deep merge on the defaults and options?

I think that exposing defaults is simpler in terms of implementation and gives more control to the user.
Edit: It would also mean no breaking changes.
