How to use

First, you must initialize the SDK. Find your Amplitude project's API Key in your project's Settings page and pass the first argument in the function initAmplitude. Your project's API key is required. You can pass an optional user ID and options object in this call. After initialization you can use hooks.

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import { initAmplitude } from '@valyay/use-react-amplitude';

// Option 1, initialize with apiKey only
initAmplitude('YOUR_AMPLITUDE_API_KEY');

// Option 2, initialize with user id
initAmplitude('YOUR_AMPLITUDE_API_KEY', '[e-mail]');

// Option 3, initialize with options
initAmplitude('YOUR_AMPLITUDE_API_KEY', '[e-mail]', your_options);

ReactDOM.render(
    <React.StrictMode>
      <App />
  </React.StrictMode>,
document.getElementById("root"),
);

Track event when component mounts

import React from "react";
import { useTrackOnMount } from '@valyay/use-react-amplitude';

export const Component = () => {

  // Option 1, initialize with event input only
  const {code, event, message} = useTrackOnMount('user_event');

  // Option 2, initialize with event properties
  const {code, event, message} = useTrackOnMount('user_event', {userProp: "foo"});

  // Option 3, initialize with event options
  const {code, event, message} = useTrackOnMount('user_event', {userProp: "foo"}, {insert_id: "test_insert_id"});

  // Hook return code, event and message of event
  const {code, event, message} = useTrackOnMount('user_event', {userProp: "foo"}, {insert_id: "test_insert_id"});

  // console.log(event); // {...}
  // console.log(code); // 200
  // console.log(message); // "Event tracked successfully"

  return <div>Title</div>;

};

Track event when component mounts or dependencies change

import React, { useState } from "react";
import { useTrackOnChange } from '@valyay/use-react-amplitude';

export const Component = () => {

  const [count, setCount] = useState<number>(0);

  // Initialize with event input only
  useTrackOnChange("count increase", [count]);
  
  // Hook return code, event and message of event
  const {code, event, message} = useTrackOnChange("count increase", [count]);

  // console.log(event); // {...}
  // console.log(code); // 200
  // console.log(message); // "Event tracked successfully"

  return (
    <div>
        <button onClick={()=>{setCount(count+1);}}>click</button>
  </div>
  );

};

Track event when only dependencies change

import React, { useState } from "react";
import { useTrackOnUpdate } from '@valyay/use-react-amplitude';

export const Component = () => {

  const [count, setCount] = useState<number>(0);
  
  // Initialize with event input only
  useTrackOnUpdate("count increase", [count]);
  
  // Hook return code, event and message of event
  const {code, event, message} = useTrackOnChange("count increase", [count]);
  // console.log(event); // {...}
  // console.log(code); // 200
  // console.log(message); // "Event tracked successfully"
  
  return (
    <div>
        <button onClick={()=>{setCount(count+1);}}>click</button>
  </div>
  );

};
