Description

Related:#6279

I have added theallowArray option torestrict-template-expressions in#8389.

Now, I'd like to discuss other things that may be useful to put in a string. The most common case for me is stringifyingURLSearchParams,Date andBuffers, but there could be potential for others as well.
Some questions for discussion:

• Do we add a new optionignoredTypeNames? (I have created a draft PRfeat: addallow option forrestrict-template-expressions #8556 implementing this)
• What will be the default value for this option?
• What does this mean for theno-base-to-string rule, which is becoming increasingly similar to this rule?

Fail

declareconstmaybeParams:URLSearchParams|undefined;fetch(`https://myapi.com?${maybeParams}`);

Pass

declareconstdefinitelyParams:URLSearchParams;fetch(`https://myapi.com?${definitelyParams}`);
