How to run ONLY tslint?

[stevenmusumeche]

Is there a way that I can run tslint directly without running the build command?

[wmonk]

Potentially

`npm bin`/tslint

[sebald]

You could add a script to your package.json. For example:

"scripts": {
  ...
+  "lint": "tslint --exclude **/*.d.ts src/**/*.ts src/**/*.tsx",
}

That does work, however it appears we need to update the tslint version to the latest? I am getting this error which seems to be fixed in later versions?

I didn't install tslint on my own, since it comes with the react-scripts-ts :)

[stevenmusumeche]

Yes, that's what I mean. The version of tslint in this repo is an older one. I'm requesting that it be updated to (maybe) solve this issue.

[sebald]

But I have an old tslint too then and it works. My lock files tells me that for the dependency: tslint@^5.2.0 it installed version 5.5.0.

Guess this is a more general issue with tslint and was fixed here: palantir/tslint@a479f43

Regenerating your installed should five you a newer tslint version (e.g. yarn upgrade-interactive).

Excuse my offtopic but I would like just the contrary. How can I run (not build) the app without tslint? thanks

[patrickmdnet]

To run lint without build, you can run the version of tslint that's part of your package.

node_modules\.bin\tslint --type-check --project .

[stevenmusumeche]

@patrickmdnet that does work, however it causes the same error I posted above

Stevens-MacBook-Pro-2:embed stevenmusumeche$ ./node_modules/.bin/tslint --type-check --project .
