[birkskyum]

jiti - GitHub

What version of Bun is running?

0.7.3

What platform is your computer?

Darwin 22.5.0 arm64 arm

What steps can reproduce the bug?

• Create a typescript file (can even be left empty): index.ts
• Run the file with jiti: bun --bun x jiti index.ts

What is the expected behavior?

The file will be ran. If empty, no output expected.

What do you see instead?

Additional information

This is blocking:

• Support Histoire (Vite framework for UI stories) #3787

Related to:

• Bun compatibility/bypass unjs/jiti#154

[paperdave]

Should be fixed now, but I notice Jiti runs extremely slow because Bun ends up re-transpiling the code when running it While it works for compatibility, really should just be using import("./module.ts") or bun run.

i mispoke there is an extra detail i didnt consider but it's a one line change and will be done next few minutes
