Support for esbuild or swc

See original GitHub issue

🚀 Feature Proposal

Hi, I started with ts-jest on my project, but found startup performance to be unacceptable. I think this is because ts-jest compiles my entire project in order to run tests. There are compilers with significantly better performance, namely esbuild and swc.

swc-node/jest is decent but doesn’t cache dependency tree, which means large repos have TONS of duplication compilation.

So maybe an opportunity here? I’m not saying it will be easy!

Definitely those 2 have lots of possibilities to solve the performance problem. They are currently the new trend as well.

We have thought about that. Probably something like an experimental mode to turn on/off which allows using those 2.
