Typescript build getting errors from node_modules folder

Question

I am running a typescript build and getting errors in node_modules. Why isn't it ignoring this folder? I have it in the exclude section of my tsconfig.json. The really strange thing is that I have another project that I have done a file comparison with and it does not throw these errors even though gulpfile.js, tsconfig.json and the node_modules folders are identical. What else can I check?

Errors:

Answer 1

I was struggling with this as well.

I added the following to the top of the TS file that contained the import {bootstrap} line:

///<reference path="../node_modules/angular2/typings/browser.d.ts"/> 

Your path may be different of course for that file.

Artichoke

This is very useful (+1), and if following the quickstart on angular.io, just referencing the top level typings directly works too: /// <reference path="../typings/browser.d.ts" /> – Suburbanite

Has Any one found a solution ...ive tried all ways.all i get is cannot find map,set,expect .... – Rotow

Well, it is considered that <reference> tag is a bad practice. Here is an article that Minko Gechev wrote about this exact error. Here is another article that explains the whole packaging process. – Silin

Answer 2

You can add the skipLibCheck property with true value into your tsconfig.json:

{
  "compilerOptions": {
    [...]
    "skipLibCheck": true
  },
  "include": ["./src/**/*.*"],
  "exclude": [
    "node_modules"
  ]
}

With this property will skip the type checking into declaration files (*.d.ts)

Thank you!! This was the right answer (for me anyway). I am trying to use types for a js project, within VSCode at work - not fully wanting to opt-in to ts just yet, and this fixed my issue. – Ephesian

Should be top answer IMHO. It's not very obvious that exclusion of node modules is not enough to get rid out of the library-dependant compilation errors. – Disgruntle

Answer 3

If you're targeting ES5, add "node_modules/typescript/lib/lib.es6.d.ts" to tsconfig.json file :

{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es5",
        "noImplicitAny": false,
        "outDir": "built",
        "rootDir": ".",
        "sourceMap": false
    },
    "files": [
      "helloworld.ts",
      "node_modules/typescript/lib/lib.es6.d.ts"
    ],
    "exclude": [
        "node_modules"
    ]
}

Newbie comment. Doing this in visual studio 2015 got me 43k new typescript build errors. – Tentative

This worked for me when some modules said they couldn't find their dependencies. – Goop

With this line of code you prevent TypeScript to check types of other files. – Senility

Answer 4

While this solution

/// <reference path="../typings/browser.d.ts" />
import {bootstrap} from 'angular2/platform/browser';
import {AppComponent} from './app/main';

bootstrap(AppComponent);

works well, wenn using gulpjs I prefer however instead of populating source file with comments, an addition of typings file directly to the source of the corresponding gulpjs task, like for example:

gulp.task('typescript', function () {
  return gulp
    .src([
      'typings/browser.d.ts',
      tsSrc + '**/*.ts'
    ])
    .pipe(sourcemaps.init())
    .pipe(typescript(tscConfig.compilerOptions))
    .pipe(sourcemaps.write('.'))
    .pipe(gulp.dest(appSrc + 'js/'));
});

Answer 5

In RC1 demo, the shim is provided by the core-js module and type definitions are managed by the typings tool. Adding typings/index.d.ts to gulp.src should fix the issue:

function buildTypeScriptFn(files) {
  files = files || ['app/**/*.ts','typings/index.d.ts'];

  return function () {
    var tsResult = gulp.src(files)
      .pipe(changed(paths.dirs.build, { extension: '.js' }))
      .pipe(ts(tscConfig.compilerOptions));

    return merge(tsResult.dts, tsResult.js)
      .pipe(gulp.dest(paths.dirs.build));
  }
}

gulp.task('ts', buildTypeScriptFn());

Answer 6

i had the same problem, just try running not with "npm start", but with "npm run lite". Its much more convenient to use.

this worked for me. will it have any problems in the future? – Dissolvent
