Introduction

React native component to show confetti. It can be used as raining snow effect animation, with option to use unicode, emoji, or image as the flying pieces.

This is some example

snow effect

(the animation is not lagging. it's because you need to wait for the gif asset to load)

shake effect

(the animation is not lagging. it's because you need to wait for the gif asset to load)

Getting Started

Dependencies

To be able to dynamically enable confetti or to change the character, your react native app must:

1. Install react-native-firebase (the Core module and Remote Config module)

2. Set up your app to use Firebase

3. Create 5 parameters with value of string in your project's remote config:

   | parameter | example value | description | | --------------------- | ------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | confetti_enabled | 1 | set 1 to enable, set 0 to disable | | confetti_image_name | snowflake | if it has value, the flying piece of the Confetti will use this parameter instead of confetti_character. if you want to use character instead, set this parameter to empty string. Further explanation in using image will be given in next section | | confetti_character | ❅ | set this value with any character or unicode / emoji. eg: ❅, ❤️, 🏮. if parameter confetti_image_name is not empty string, this parameter is not being used | | confetti_type | shake | set the value shake or snow. With snow, you just use vertical falling animation. With shake you get additional horizontal shake animation. | | confetti_color | #6FC4C7 | hexadecimal value string |

Installation process

Using npm:

npm i @hyperjumptech/react-native-confetti --save

or using yarn:

yarn add @hyperjumptech/react-native-confetti

Usage

Minimal usage

import package

import {Confetti} from '@hyperjumptech/react-native-confetti';

then put the component inside render

<Confetti isEnabled={true} color={'#6FC4C7'} character={'❅'} />

With firebase remote config usage

import package

import {
  Confetti,
  fetchConfettiFromFirebase,
} from '@hyperjumptech/react-native-confetti';

define state to hold the parameters

state = {
  confetti: {
    confetti_type: 'snow',
    confetti_color: '',
    confetti_character: '',
    confetti_image_name: '',
    confetti_enabled: false,
  },
};

define the parameters and call function to get data from firebase remote config

const keys = [
  'confetti_type',
  'confetti_color',
  'confetti_character',
  'confetti_enabled',
  'confetti_image_name',
];

fetchConfetti(keys).then((data) => {
  const confetti = {
    confetti_type: data.confetti_type,
    confetti_color: data.confetti_color,
    confetti_character: data.confetti_character,
    confetti_enabled: data.confetti_enabled === '1' ? true : false,
    confetti_image_name: data.confetti_image_name,
  };
  this.setState({confetti});
});

then put component inside render

const {confetti} = this.state;

return (
  <Confetti
    isEnabled={confetti.confetti_enabled}
    color={confetti.confetti_color}
    character={confetti.confetti_character}
    effect={confetti.confetti_type}
  />
);

Usage with image instead of character

If you wish to use image, you can use image from predefined asset (not a dynamic url). So the step is same as above with additional step to define image path and size:

const images = {
  snowflake: {
    path: require('../../path_to_snowflake_image_asset.png'),
    size: 24,
  },
  heart: {
    path: require('../../path_to_heart_image_asset.jpeg'),
    size: 24,
  },
};

then add the imageComponent props

<Confetti
  ...
  imageComponent={
  !!confetti.confetti_image_name ? (
    <Image
      source={images[confetti.confetti_image_name].path}
      style={{
        width: images[confetti.confetti_image_name].size,
        height: images[confetti.confetti_image_name].size,
      }}
    />
  ) : (
    undefined
  )
}
/>

API references

Props:

| props | type | required | description | | -------------- | ----------------------- | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | isEnabled | boolean | yes | to enable or disable the confetti | | color | string | yes | define color of character. If you use emoji or image, the color will have no effect even if it has value | | character | string | no | the flying pieces. default character is snowflake ❅. you can use any unicode character or emoji. if there is imageComponent this props will have no effect even if it has value | | imageComponent | ReactNode | no | the flying pieces (will override character props) in form of react component for example: Image | | effect | enum: [snow, shake] | yes | snow to get only vertical falling animation , shake to get additional horizontal shaking animation |
