How can I enforce filename and folder name convention in typescript eslint?

I am using eslint for typescript convention. And I checked this rule https://github.com/typescript-eslint/typescript-eslint/blob/master/packages/eslint-plugin/docs/rules/naming-convention.md which only works for code.

I am looking for a rule which can enforce filename to be camelCase and folder name to be snake_case. How can I set this rule in typescript?

Solution 1:

Eslint doesn't implement by default the file name check, see this github issue from 2015.

Some plugins do like eslint-plugin-unicorn or eslint-plugin-filenames.

Because Tslint is now deprecated, they created the project typescript-eslint, which is handling file naming casing, you could check it out :)

Solution 2:

Adding a few more resources after the fact - I found for filenames, that eslint-plugin-filename-rules worked well.

For enforcing eslint on folders, eslint-plugin-folders worked for me for directories with files in it. The documentation says only .js and .jsx files but .ts and .tsx files worked for me as well.
