Is it possible to enable immutability rules only in certain files?

[MichaelTontchev]

I'm fine with most of my interfaces allowing mutation - I just want my Redux state definition to enforce recursive mutability. Can the reaonly interface rule be turned on only in that file?

Yes, there are several ways to run tslint rules for only a specific set of files.

The CLI version of tslint has this syntax:

tslint [options] [file ...]

So you can just specify the files you want it to run for. For example in a package.json script.

Another way is to have nested tslint.json files. Say that you have one tslint.json in the root that contains your normal rules, and then you put another tslint.json in the subfolder that contains your Redux interface declarations that has the extra readonly rules. Then that tslint.json overrides the one on the root level. So you can run tslint once and get different rules in different folders.

I'm closing this now as it is answered but feel free to re-open should there be follow up questions.
