Interfaces not checked?

[SDohle]

Hi,

the tslint-loader doen't check Rules in my typescript interfaces:

import {Component} from '@angular/core';
export interface Test {
  Test : string;
}

Running tslint standalone results in two warnings:

src/app/home/home.interface.ts[1, 9]: Unused import: 'Component'
src/app/home/home.interface.ts[4, 7]: expected nospace before colon in property-declaration

I use emitErrors: true and failOnHint: true to break the build. But during the webpack build with tslint-loader as a preloader no warnings/errors are emitted for violations in interfaces.

I also have this issue. Are there any plans for fixing?

[sonicoder86]

@SDohle @DarkXaHTeP is it still present with latest version?

[SDohle]

I can't test it, version 3.2.0 isn't working with my setup:

OK, updating to TSLint 4.0.1 fixes this problem. But i use the codelyzer package and that is not yet compatible with tslint 4.0.1.

[SDohle]

Problem is fixed. Thank you!

I seem to be running into this issue with tslint 4.2.0 and tslint-loader 3.3.0.
Really odd that it skips over modules with interfaces.

[GaryB432]

Like @jrparish I am having the problem with the same versions. I wonder if we can reopen. Is this project maintained? I see #40 is closed. using webpack 2.2.0-rc.3

edit: I see #40 is closed because somebody picked up the repo! thanks!

[SDohle]

Got this issue again, too.
Running "tslint": "4.2.0" and "tslint-loader": "3.3.0".

Please reopen, @BlackSonic

[genaro-picazo]

+1 for reopening. Seeing the issue in tslint 4.4.2 and tslint-loader 3.3.0.

[sonicoder86]

Can you add an example repository? There is a test for it also in the loader repository.

[GaryB432]

I didn't see the test for it in the loader repository. I cut and pasted a small project. I hope it helps.

Observe the console section to see the violations of interface-name only under npm run lint and not under npm run build.

console

$ npm run build && npm run lint
