## Running the Sample Locally

Before you can run this sample on your local machine, you need to have Git and Node.js installed. If they’re not already installed, follow [these instructions](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm) to get them set up.

Once you have Git and Node.js installed, you can run the sample by following these steps:

1. Clone the repository and navigate to the directory of the sample.

2. Install the necessary dependencies.

3. Start running the sample.

Here are the commands you can use in your terminal to do this:

```shell
git clone -b sample/geolocation-api https://github.com/woosmap/js-samples.git
cd js-samples
npm i
npm start
```

You can experiment with other samples by switching to any branch that starts with the pattern `sample/SAMPLE_NAME`.

```shell
git checkout sample/SAMPLE_NAME
npm i
npm start
```
