TSLint Origin Ordered Imports Rule

Custom rule for tslint

Strict order for imports ("Lib import" must be higher than "User import") + your own import groups defined by regexps.

🚀 This plugin needs minimum configuration to start:

npm i -D tslint-origin-ordered-imports-rule

tslint.json

"rulesDirectory": [
    "node_modules/tslint-origin-ordered-imports-rule/dist"
],
"rules": {
    "origin-ordered-imports": [ true ]
}

Wrong:

import MyClass from './my-class';
import * as _ from 'lodash';

Right:

import * as _ from 'lodash';
import MyClass from './my-class';

Then you might set one-blank-line option to require a blank line between import groups. In such a case, the previous code becomes wrong.

Right:

import * as _ from 'lodash';

import MyClass from './my-class';

Apart from one-blank-line, there are a few other options:

• no-blank-lines
• at-least-one-blank-line
• any-number-of-blank-lines

This plugin was created to be as simple as possible, with zero-configuration. It could still be used in that way, but if you need more configurable tool just define the array which describes your own order.

tsconfig.json

"rules": {
    "origin-ordered-imports": [ 
        true, 
        "one-blank-line",
        [
            "lib",
            "^@custom/.+",
            "user"
        ] 
    ]
}

Wrong:

import * as _ from 'lodash';
import * as moment from 'moment';

import MyClass from './my-class';
import MyClass2 from './my-class2';

import Foo from '@custom/foo';
import Bar from '@custom/bar';

Right:

import * as _ from 'lodash';
import * as moment from 'moment';

import Foo from '@custom/foo';
import Bar from '@custom/bar';

import MyClass from './my-class';
import MyClass2 from './my-class2';

Actually, you can omit lib and user items as they will be added automatically to the beginning and the ending respectively.

Testing

To test the rule just run:

npm run compile
npm run test
