Unclear imports should be aliased for clarity

---

Source code

Options

aliases

A list of all the imports that you want to alias for clarity. Every alias should be declared in the following format:

{
  "package": "rxjs",
  "imported": "of",
  "local": "observableOf"
}

Examples

Valid code

correctly aliased imports

import { of as observableOf } from 'rxjs';

With options:

{
  "aliases": [
    {
      "package": "rxjs",
      "imported": "of",
      "local": "observableOf"
    }
  ]
}

enforce unaliased import

import { combineLatest } from 'rxjs';

With options:

{
  "aliases": [
    {
      "package": "rxjs",
      "imported": "combineLatest",
      "local": "combineLatest"
    }
  ]
}

Invalid code & automatic fixes

imports without alias

import { of } from 'rxjs';

        

Will produce the following error(s):

This import must be aliased

Result of yarn lint --fix:

import { of as observableOf } from 'rxjs';

imports under the wrong alias

import { of as ofSomething } from 'rxjs';

        

Will produce the following error(s):

This import uses the wrong alias (should be {{ local }})

Result of yarn lint --fix:

import { of as observableOf } from 'rxjs';

disallow aliasing import

import { combineLatest as observableCombineLatest } from 'rxjs';

        
With options:

```json
{
  "aliases": [
    {
      "package": "rxjs",
      "imported": "combineLatest",
      "local": "combineLatest"
    }
  ]
}

Will produce the following error(s):

This import should not use an alias

        
Result of `yarn lint --fix`:
```typescript
import { combineLatest } from 'rxjs';
