# Notifications POC

POC for frontends to get notified of blockchain data that they're interested in. This project uses [Subquery](https://subquery.network/) to notify web browsers when the Cosmos Hub wallet having the address cosmos19vf5mfr40awvkefw69nl6p3mmlsnacmm28xyqh receives cryptocurrency.

## Installation

1. Install [Docker](https://docs.docker.com/get-docker/).

2. Install the latest [Node.js](https://nodejs.org/en/download/) LTS.

3. Clone the repo using one of the following methods:

    - SSH:

        ```shell

        git clone [email protected]:leapwallet/notifications-poc.git

        ```    

    - HTTPS:

        ```shell

        git clone https://github.com/leapwallet/notifications-poc.git

        ```

4. Install the backend:

    ```shell

    cd notifications-poc/backend && yarn && yarn codegen && yarn build

    ```

5. Install the frontend:

    ```shell

    cd ../frontend && npm i

    ```

## Usage

1. Start the backend:

    ````shell

    cd backend && yarn start:docker

    ````

2. Start the frontend in another terminal session:

    ```shell

    cd frontend && npm start

    ```

    Open the URL printed to the console in your browser, and allow notifications to see the demo.

3. Once you're done:

    1. In the frontend's terminal session, enter `Ctrl+C`.

    2. In the backend's terminal session:

        1. Enter `Ctrl+C`

        2. Shut down the backend:

            ```shell

            docker compose down

            ```
