How should I go about avoiding the use of "any" in my state interfaces, such as

export interface ITestState{
  listItems : any // this triggers a lint warning

when it's not exactly known what fields are defined for a list?

lint gives the warning

error @typescript-eslint/no-explicit-any: Unexpected any. Specify a different type.

Of course, nothing breaks when using "any", but I'm looking to understand what would be the best way to deal with this warning.

You can disable (and re-enable specific) eslint warnings at the line, block, file, an project levels. Here's how to disable the warning for the case you mentioned:

export interface ITestState{
  listItems : any // eslint-disable-line @typescript-eslint/no-explicit-any

  • Thank you Rob. I know it can be disabled, but I would like to know how to define the listItems object without using 'any'. It can be defined as an object, but then you run in to errors elsewhere in your code like Property 'x' does not exist on type

  • I don't think there's an alternative to using any if you don't know what fields are going to be in the list. You could change the type of listItems to any[] so the code at least knows it's working with an array. Dec 11, 2022 at 12:35
