  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
