So many errors in typescript code

[polRk]

After clone, i see many errors and can't build project.

I think, you should use eslnit + tsc with right configs.
tsconfig.json

    "target": "ES2017",
    "module": "commonjs",

}

.eslintrc.js

module.exports = {
  parser: '@typescript-eslint/parser',
  extends: [
    'plugin:@typescript-eslint/recommended',
    'plugin:prettier/recommended',
    'prettier/@typescript-eslint',
  ],
  parserOptions: {

    sourceType: 'module',
  },
};

This seems to be specific to your editor setup, there are no errors as demonstrated by the builds in travis.

[polRk]

No, it's not all ide setup errors. For example:

My variant ( valid typings )

export class Queue<T = any> extends QueueGetters {
  token = v4();
  limiter?: RateLimiterOptions;
  jobsOpts?: JobsOptions;

Your variant ( invalid typings )

export class Queue<T = any> extends QueueGetters {
  token = v4();
  limiter: RateLimiterOptions = null;
  jobsOpts: JobsOptions;

TS2322: Type 'null' is not assignable to type 'RateLimiterOptions'.

[manast]

You are probably compiling with different settings. As you see the library compiles just fine in Travis, otherwise the tests would not pass.

[manast]

For the record with latest code in master as now:

[polRk]

You assign variable with type RateLimiterOptions the value null. In my opinion, this is a mistake

[polRk]

Pls, use RateLimiterOptions | null type. You mislead other developers with your code

[polRk]

In your typings, limiter - is always exists and can't be null. But it false
