fix: replace tsutils with ts-api-tools #6428

merged 5 commits into from Feb 6, 2023


Copy link

PR Checklist


Uses ts-api-tools as a drop-in replacement for tsutils.

Note that tsutils provides some is* typeguards that are now exposed by TypeScript (e.g. ts.isBinaryExpression). I've gone ahead and switched to the TypeScript versions in this PR. Once #5573 is in we'll have CI checking to make sure our TypeScript version range supports them.

@JoshuaKGoldberg JoshuaKGoldberg added this to the 6.0.0 milestone Feb 6, 2023

Can we trust this new package? I've heard some terrible things about the maintainer.

ts-api-tools formats its output files as .js with ES modules. But it also includes an additional set of .cjs files for CJS users. This allows Jest to consider .cjs files (which it didn't before) - and look at them before .js files.

Note that I renamed the package to ts-api-utils in JoshuaKGoldberg/ts-api-utils#28. We don't have to take action on the rename just yet. Just a note for the next time we need to bump the package version.
