A HostedHooks Sample To-Do app using Next.js

This example app shows how to integrate HostedHooks with a react-based Next.js application to send webhooks when events are triggered.

Demo

https://nextjs-hostedhooks-demo.herokuapp.com/

How to use

git clone https://github.com/HostedHooks/nextjs_sample_app.git

cd nextjs_sample_app

Configuration

Step 1. Create an account on hostedhooks

First, create an account on hostedhooks.

Step 2. Generate an app for your webhooks

After creating your account, you need to generate a new app where events will occur. This app is what your webhook subscribers will be subscribing to.

Step 3. Create a Webhook Event for your app instance

Next, go to your app and create a Webhook Event for your app that subscribers can subscribe to.

In this example, we created 4 events based on a traditional todo app:

• todo.created - triggered whenever a new todo is created.
• todo.completed - triggered whenever a todo is completed.
• todo.uncompleted - triggered whenever a todo is uncompleted.
• todo.deleted - triggered whenever a todo is deleted.

Note: The events being sent from your application must match the events created in your app instance and they must be created first.

Step 4. Set up environment variables

Next, copy the .env.local.example file in root directory to .env.local (which will be ignored by Git):

cp .env.local.example .env.local

Then set each variable on .env.local:

• NEXT_PUBLIC_HOSTEDHOOKS_API_KEY must be the API Key from your account settings.
• NEXT_PUBLIC_APP_UUID must be the ID of your app instance.

Your .env.local file should look like this:

NEXT_PUBLIC_HOSTEDHOOKS_API_KEY=...
NEXT_PUBLIC_APP_UUID=...

Note: These environment variables must be prefixed by NEXT_PUBLIC_ as they will be exposed and run in the browser (Documentation).

Step 5. Running in development mode

npm install
npm run dev

# or

yarn install
yarn dev

Your app is now running at http://localhost:3000.

Triggering an event:

When your app triggers an event, you can send a webhook message by calling your webhook function:

const handleOnDeleteTodoClick = (id) => {
  // deleting todo locally, you may want to call an API
  const todo = deleteTodo(id);

  // you can pass in whatever data you want to send with the event
  sendWebhookMessage('todo.deleted', todo);
};

Building your webhook message:

In your webhook message, you can form the data object as you want:

export default function sendWebhookMessage(event, todo) {
  var url = new URL(
    `https://www.hostedhooks.com/api/v1/apps/${process.env.NEXT_PUBLIC_APP_UUID}/messages`
  );

  // message headers
  var myHeaders = new Headers();
  myHeaders.append('Authorization', `Bearer ${process.env.NEXT_PUBLIC_HOSTEDHOOKS_API_KEY}`);
  myHeaders.append('Content-Type', 'application/json');

  // data to be sent with an event, ex: user session data
  const user = {
    id: 'user_id',
    role: 'team_manager',
  };

  // webhook message
  var messagePayload = JSON.stringify({
    data: {
      user: user,
      todo: todo, // todo data
    },
    version: '1.0',
    event_type: event, // `todo.deleted`
  });

  var requestOptions = {
    method: 'POST',
    headers: myHeaders,
    body: messagePayload,
    redirect: 'follow',
  };

  fetch(url, requestOptions)
    .then((response) => response.text())
    .then((result) => console.log(result))
    .catch((error) => console.error(error));
}

Now your app is ready to go, delete or create a new todo, and open your devtools to see the result.

You should get a 201 Created success status response code which indicates that your webhook message has been sent, and your subscribers has been notified.
