Installation

Run the following command from the root of your project:

ns plugin add @nativescript-community/ui-lottie

Usage

NativeScript (Core)

XML

<Page
    xmlns="http://schemas.nativescript.org/tns.xsd"
    xmlns:Lottie="@nativescript-community/ui-lottie" navigatingTo="navigatingTo" class="page">
    <StackLayout>
        <Lottie:LottieView src="PinJump.json" height="130" loop="true" autoPlay="true" loaded="yourLoadedEvent" />
    </StackLayout>
</Page>

TS

import { LottieView } from "@nativescript-community/ui-lottie";

public yourLoadedEvent(args) {
    this._myLottie = args.object as LottieView; /// this is the instance of the LottieAnimationView
}

---

NativeScript Angular

Module

First you need to include the NativeScriptLottieModule in your app.module.ts

import { NativeScriptLottieModule} from '@nativescript-community/ui-lottie/angular';

@NgModule({
    imports: [
        NativeScriptLottieModule
    ],
    ...
})

XML

<StackLayout>
    <LottieView width="100" height="150" [src]="src" [loop]="loop" [autoPlay]="autoPlay" (loaded)="lottieViewLoaded($event)">     </LottieView>
</StackLayout>

Component

import { Component } from '@angular/core';
import { LottieView } from '@nativescript-community/ui-lottie';

@Component({
  templateUrl: 'home.component.html',
  moduleId: module.id
})
export class HomeComponent {
  public loop: boolean = true;
  public src: string;
  public autoPlay: boolean = true;
  public animations: Array<string>;

  private _lottieView: LottieView;

  constructor() {
    this.animations = [
      'Mobilo/A.json',
      'Mobilo/D.json',
      'Mobilo/N.json',
      'Mobilo/S.json'
    ];
    this.src = this.animations[0];
  }

  lottieViewLoaded(event) {
    this._lottieView = <LottieView>event.object;
  }
}

---

NativeScript Vue

Bootstrap

If you want to use this plugin with Vue, do this in your app.js or main.js:

import LottieView from '@nativescript-community/ui-lottie/vue';

Vue.use(LottieView);

This will install and register LottieView component to your Vue instance and now you can use the plugin.

Component

<template>
    <Page class="page">
        <StackLayout>
            <LottieView height="130" src="PinJump.json" :loop="true" :autoPlay="true" @loaded="lottieViewLoaded"></LottieView>
        </StackLayout>
    </page
</template>

<script>
    export default {
        methods: {
            lottieViewLoaded(args) {
                this._lottieView = args.object;
            },
        },
        data() {
            return {
                _lottieView: null,
            }
        }
    };
</script>

Assets

🔥 You can find animations in the sample-effects folder.

Android

Place your animation files in the NS app's app/App_Resources/Android/src/main/assets folder.

Note: In a nativescript-vue project the above folder may not exist. Place the files in platforms/android/app/src/main/assets.

iOS

Place your animations files in your app/App_Resources/iOS/ folder.

Properties (bindable)

Demos and Development

Repo Setup

The repo uses submodules. If you did not clone with --recursive then you need to call

git submodule update --init

The package manager used to install and link dependencies must be pnpm or yarn. npm wont work.

To develop and test: if you use yarn then run yarn if you use pnpm then run pnpm i

Interactive Menu:

To start the interactive menu, run npm start (or yarn start or pnpm start). This will list all of the commonly used scripts.

Build

npm run build.all

WARNING: it seems yarn build.all wont always work (not finding binaries in node_modules/.bin) which is why the doc explicitly uses npm run

Demos

npm run demo.[ng|react|svelte|vue].[ios|android]

npm run demo.svelte.ios # Example

Demo setup is a bit special in the sense that if you want to modify/add demos you dont work directly in demo-[ng|react|svelte|vue] Instead you work in demo-snippets/[ng|react|svelte|vue] You can start from the install.ts of each flavor to see how to register new demos

Contributing

Update repo

You can update the repo files quite easily

First update the submodules

npm run update

Then commit the changes Then update common files

npm run sync

Then you can run yarn|pnpm, commit changed files if any

Update readme

npm run readme

Update doc

npm run doc

Publish

The publishing is completely handled by lerna (you can add -- --bump major to force a major release) Simply run

npm run publish

modifying submodules

The repo uses https:// for submodules which means you won't be able to push directly into the submodules. One easy solution is t modify ~/.gitconfig and add

[url "ssh://[email protected]/"]
	pushInsteadOf = https://github.com/
