How to get version from package.json in angular library

I can't include version from package.json in angular's library but it works in a project. I use import like that:

import { version } from '../../package.json';

and get the following error:

ERROR: error TS6059: File '/Users/.../library/package.json' is not under 'rootDir' '/Users/.../library/src'. 'rootDir' is expected to contain all source files.

An unhandled exception occurred: error TS6059: File '/Users/.../library/package.json' is not under 'rootDir' '/Users/.../library/src'. 'rootDir' is expected to contain all source files.

See "/private/var/folders/tw/z8v0wkt50g5876740n99hzy00000gp/T/ng-0JDpjC/angular-errors.log" for further details.

The way through require includes the whole package.json which incur security risks. import { version } from '../../package.json' includes only the version number but works for angular applications not libraries.

The solutions proposed under this post do work, however, they pose security threats as the full package.json file wil be exposed on the client side. This should be a more secure solution: In an Angular (>= 2) application, how to include version information from npm package.json file into the compiled output files?

As Jozef mentioned make sure you turn on the "resolveJsonModule": true in your tsconfig.json.

import libraryPackage from '../path/to/package/package.json';

Another old solution is to make an http call and load the package.json file content. This can be useful when your file content dynamically changes (example your deploy server updates the file content when it gets deployed).

You can import it like a regular module:

import { version } from 'package.json'

But be sure to add "resolveJsonModule": true to compilerOptions inside your tsconfig.json.

What about this code : 

const packageJson = require('../../package.json');
console.log(packageJson.version);
