Grasp – JavaScript structural search, replace, and refactor

SSR (structural search and replace) is one of the greatest but overlooked features of IntelliJ. It helps with refactorings a lot

I played around with jscodeshift and ASTExplorer a few weekends ago. I found it to be fairly opaque. All I was hoping to do was remove a wrapping function and replace it with its child/children. The documentation for jscodeshift is fairly rudimentary. I had high hopes of creating examples and submitting them as PRs... but alas, a weekend is only so long. Perhaps this weekend will have me giving it another shot with this tool.

I've been able to use this for some basic stuff like renames, but still trying to work on a way to convert old style string concats:

    'foo'+bar+'baz'

to current JS template literals:

    `foo${bar}baz`

If you do it first, let me know! Otherwise I'll throw mine on npm.

I remember running across this when I was researching jscodeshift, though that seems to have a steeper learning curve.

Exciting tool. I look forward to working with it.

This is honestly great.

It's funny to see how many tools a non-lisp programmer needs...
