Unable to utilize Stats.js with @angular/cli version 1.4.4

Attempting to utilize @types/stats with @angular/cli following the guidance at https://github.com/angular/angular-cli/wiki/stories-third-party-lib. However, encountering a tslint error when trying to

import * as STATS from 'stats.js'
.

[ts] Module '"stats.js"' resolves to a non-module entity and cannot be imported using this construct.

Referencing index.d.ts of @types/stats.

declare class Stats {
    REVISION: number;
    dom: HTMLDivElement;
    /**
     * @param value 0:fps, 1: ms, 2: mb, 3+: custom
     */
    showPanel(value: number): void;
    begin(): void;
    end(): number;
    update(): void;
}

declare module "stats.js" {
    export = Stats;
}

Regarding src/Stats.js(Stats.js itself)

https://github.com/mrdoob/stats.js/blob/master/src/Stats.js

The issue may stem from @types/stats utilizing export = style exporting.

Hence, considering the use of

import Stats = require('stats.js')
But by default, @angular/cli employs "module": "es2015".

Seeking advice on how to properly import it?

Answer №1

If you have double-checked that all the installations were done correctly.


npm install stats-js
npm install @types/stats-js

You should be able to use it with the following import statement: import * as STATS from 'stats'; Make sure not to include the '.js' extension.

Answer №2

If you're looking to use the @types/stats.js package that corresponds to the stats.js library, you can easily install both by following these steps:

npm install --save stats.js
npm install --include=dev @types/stats.js

After installation, you can integrate the library and its types into your Typescript code like so:

import Stats from 'stats.js';

... continue with your code ...
