it works , when i use alias in my project.But it occurs an error in ts file.

[Jax97]

// gulpfile.js

gulp
 .src(entry)
 .pipe(alias({ configuration: tsProject.config }))
 .pipe(tsProject())
 .pipe(gulp.dest('./dist'));

// src/server/controllers/index.ts

import IndexController from '@/controllers/IndexController'; // cannot find module “@/controllers/IndexController” or other type declarations

// src/server/controllers/IndexController.ts

import Koa from 'koa';

export default class IndexController {
 constructor() {}
 async actionIndex(ctx: Koa.Context, next: Koa.Next) {
 const books = new Books();
 const res = await books.getData();
 ctx.body = res;
 }
}

// tsconfig.json

{
 "compilerOptions": {
 "target": "es5" ,
 "module": "commonjs",
 "paths": {
 "@/controllers": ["./src/server/controllers"],
 "@/models": ["./src/server/models"]
 } ,
 "esModuleInterop": true,
 "skipLibCheck": true,
 "forceConsistentCasingInFileNames": true
 }
}

Although the app run normally, I want to resolve the errors in index.ts

If you're getting TypeScript errors, this doesn't seem to be an issue with this plugin. TypeScript errors are an issue with your own TypeScript configuration typically.

Well, same here... TS is working fine with my files, when I try to build the gulp-ts-alias get too far...
When it has to be '../../' the lib transforms it in '../../../../'
