I get the following:

I'm using:

• _codelyzer_: 0.0.28
• _tslint_: 3.15.1
• _ts-node_: 1.3.0
• _typescript_: 2.0.2

Can I see a code snippet of the file you are running codelyzer on?

[rolandjitsu]

@preslavsh Unfortunately I run it on probably around 200+ TS files, so I am not sure where it fails. Also, due to an NDA, I am not allowed to disclose any code. And the error does not seem to provide any clue which file that may be.

[rolandjitsu]

At least I can tell you that the following rules cause that error:

{
    "component-selector-name": [true, "kebab-case"],
    "component-selector-type": [true, "element"],
    "component-selector-prefix": [true, "infarm"]
}

[preslavsh]

I have created PR for that, but it's only a smart guess.

[rolandjitsu]

Ok, so it boils down to this:

private static createComponent(selector: string, template: string): any {
    @Component({selector, template})
    class DynamicComponent {}
    return DynamicComponent;
}

I have a service that creates dynamic modules/components.

[rolandjitsu]

The following does not throw:

@Component({selector: selector, template: template})

But then I get errors for the shorthand rule:

(object-literal-shorthand) app/shared/component-builder/type-builder.service.ts[15, 15]: Expected property shorthand in object literal.
(object-literal-shorthand) app/shared/component-builder/type-builder.service.ts[15, 35]: Expected property shorthand in object literal.

@rolandjitsu thanks for digging into this! With the information you provided we should fix it in a day or two.

[rolandjitsu]

@mgechev no worries, @preslavsh pointed me in the right direction.

[mgechev]

@rolandjitsu I will not publish to npm in the next a couple of days. I'm planning a bigger release which includes template support.
