Typescript error - Type 'Name' does not satisfy the constraint 'string'

See original GitHub issue

I’m seeing the following Typescript error:

ERROR in [at-loader] ./node_modules/jss/src/index.d.ts:8:78
    TS2344: Type 'Name' does not satisfy the constraint 'string'.
  Type 'string | number | symbol' is not assignable to type 'string'.
    Type 'number' is not assignable to type 'string'.

…which I’m circumventing by amending ./node_modules/jss/src/index.d.ts to look like this:

export type Classes<Name extends string = string> = Record<Name, string>

Er, I think that’s an issue with jss, but I’m willing to be told otherwise 😉

I’m running typescript v3.6.3, node v10.15.3 and npm v6.11.2 on different OS’s.

@bassettb if you are still having this error or anybody else in the future, I found some documentation about the “keyOfStringsOnly” in the tsconfig file. When I removed that setting, it compiled.

@sikorsky555 you sir, are an absolute star! I will admit to hacking out Name extends string | number | symbol = string for the best part of two years! Now I can move on with the rest of my life (well, if I wasn’t stuck at home on lockdown)! 😃
