Steps to Reproduce

node --import @swc-node/register/esm-register --import ./instrument.js ./src/main.ts

Expected Result

The main.ts file should be correctly executed.

Actual Result

TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts" for /Users/pascal/code/ips-hosting/api/src/main.ts

I also tried with import-in-the-middle 1.8.0 without success. Removing the instrument.js import resolves the issue.

Does it work with the loaders the other way around?

node --import ./instrument.js  --import @swc-node/register/esm-register ./src/main.ts

[timfish]

I can't even get it to work without instrument.js:

With @swc-node/register@1.9.1 and:

node --import @swc-node/register/esm-register ./test.ts

Gives me

Yes, that's an issue with version 1.9.1. you have to downgrade to 1.9.0.

For reference: swc-project/swc-node#785

[timfish]

I get the same error with v1.9.0 and v1.8.0 with Node v22

[P4sca1]

I tested using Node v22.2.0, @swc-node/register 1.9.0, and import-in-the-middle 1.8.0. The order of the loaders indeed makes a difference. Importing the JavaScript module before the SWC loader solves the ERR_UNKNOWN_FILE_EXTENSION issue.
node --env-file=.env --import ./instrument.js --import @swc-node/register/esm-register ./src/main.ts
