Rule proposal: detect useless template literal interpolation #2846
Closed
Description
Hi there,
First of all, thanks for this great set of ESLint + TS utilities, these are great!
I am unsure if I'm doing this right, because the issue template was about bug reports, but I would like to propose a new rule. Since I didn't see a template for this, I'm going to go ahead like this, and then can change it / resubmit if necessary.
What I wanted to bring up was the idea of a @typescript-eslint/no-useless-interpolation
rule, similar to the eslint/eslint#10798 proposal to ESLint, which as far as I can tell, never got implemented.
The idea would be, if there is useless interpolation with a template string, this would be an error.
Example of incorrect code:
`${'abc'}` // incorrect
const str = 'def';
`${str}` // incorrect
`123${'abc'}` // incorrect
`${'abc'}${'def'}` // incorrect
Examples of correct code:
'abc' // correct
const str = 'def';
str // correct
'123abc' // correct
'abcdef' // correct
I would suggest only doing this for strings.
Remaining template things
- I have tried restarting my IDE and the issue persists.
- I have updated to the latest version of the packages.
- I have read the FAQ and my problem is not listed.
