Can't get CustomEase to work with Angular

[marcodellabate 6 Likes (Newbie)]

Good morning, I'm making a project with Angular 5 and I've imported GSAP along with TimelineMax but I can't seem to get CustomEase to work.
The terminal doesn't give me errors but when I load the page in the browser I get the "Error: CustomEase is not defined"

Can someone explain me the exact procedure to import and use CustomEase? Maybe I'm missing something.

@marcodellabate, let us know if that thread that @Sahil shared gets you going in the right direction. I suspect it will, but don't hesitate to share details if you're still having trouble. Happy tweening!

Okay, I've tried to delete gsap to do a fresh install. I've used this code
 

npm install -S gsap @types/greensock

I've added this line to the main.ts file
 

import 'gsap';

but when I put my tweenings into app.component.ts I get this error:

 

The TimelineMax name was not found

same goes for CustomEase. Where am I going wrong?

Is that a typescript error? Those types aren't correct.

 

You can always silence the error.

declare var TimelineMax;
declare var CustomEase;

Now when I start the ng serve I get this error
 

ERROR in node_modules/@types/gsap/index.d.ts(14,5): error TS2300: Duplicate identifier 'export='.
src/typings.d.ts(6,44): error TS2300: Duplicate identifier 'export='.

EDIT: Solved by adding this line to tsconfig.json
 

    "paths" : {
      "*" : [
        "../TSProjectA/node_modules/@types/*",
        "./node_modules/@types/*",
        "*"
      ]
    },

but I keep getting the CustomEase error defined in the first post

Again...

Here is a definition for CustomEase.

 

declare class CustomEase {
    id: string;
    constructor(id: string, data: string, config?: object);
    static create(id: string, data: string, config?: object): CustomEase;
    static get(id: string): CustomEase;
    static getSVGData(ease: string | object, vars?: object): string;
    getSVGData(ease: string | object, vars?: object): string;
    getRatio(progress: Number): this;
}

I'm sorry but I'm new to angular and I still have to learn.
I added the line you provide, and while I don't get any error in VSCode, I still get a "CustomEase not defined" error in the firefox console.

It sounds like it isn't loaded. You can check if it's loaded by logging this out. It should be under easing.

 

console.log("GSAP", window.com.greensock)

There are all the easings names under easing (Back, BackIn ecc.) but I don't see any CustomEase

[OSUblake 18,475 Likes (Superhero)]

Is CustomEase inside your npm folder? If so, try importing like.

 

import * as CustomEase from "gsap/CustomEase";

 

I think the latest version of TypeScript includes an option to change how default imports work, so that might be a little different depending on your version. Not sure as haven't played around with it.

[marcodellabate 6 Likes (Newbie)]

The result is the same, even in the console log

Well can you send me a simplified version of your project so I can see what's going on? You can send me it in a PM if you don't want to post it publicly.

Is there a solution for this? I am unable to use CustomEase in a React TypeScript project. I have the latest GSAP installed via npm (2.1.2) and @types/gsap. Can anyone share an example of how to "properly" install and use CustomEase with NPM/Yarn, ideally in a React TypeScript project? It seems like React TypeScript is a huge and growing target platform that is under-support / under-documented in greensock at this time.

Hi @srapport. I'm not a TypeScript or React guy, so I'm probably the wrong person to help but I'm curious - do you just need a CustomEase TypeScript definitions file maybe? I suspect that the @types/gsap package doesn't include one.

Thank you. I found the CustomEase file via download on the website and manually included it. I would have expected it to be part of the npm/yarn installer.

Glad you figured it out. Yeah, CustomEase is a perk for folks who set up a (free) GreenSock account. It helps us foster connection with our users. Hopefully it's clear that we value community around here - it's one of the things that sets GreenSock apart. 

 

Happy tweening!
