This procedure is part of a lab that teaches you how to troubleshoot your web app with New Relic browser. If you haven't already, check out the lab introduction.
Before you can walk through the lab proper, you need to spin up your React application. Here, you:
- Spin up your React application
- Send traffic to your app with a simple load generator
Open a terminal window and clone the lab repository.
$git clone https://github.com/newrelic-experimental/relicstaurants.git
Navigate to the root directory of your application and switch to the lab directory.
$cd relicstaurants$git switch browser-pro-lab-material
Next, install dependencies, and run the application.
$npm install$npm run build$npm run newstart
This opens your Relicstaurants application in your browser.
Enter your delivery address, and search for restaurants to get started.
Here, you see a list of restaurants where you can order food.
Choose a restaurant.
Select an item or two and click on cart.
Enter the following fake card information and click Finish payment to place your order.
Your order is successfully placed.
Next, you use a simulator to generate more traffic to your application.
In another terminal window, navigate to the root directory of your application, and run the load generator.
$# Navigate to the root directiory of your simulator$cd relicstaurants/simulator$# Switch to lab branch$git switch browser-pro-lab-material$# Install the simulator's dependencies$pip3 install -r requirements.txt$# Run the simulator$python3 simulator.py====== WebDriver manager ======Current google-chrome version is 99.0.4844Get LATEST chromedriver version for 99.0.4844 google-chrome
This load generator assumes you have Google Chrome installed on your computer. If you're using a different browser, either skip this step and generate traffic manually, or install Google Chrome.
Now, that you know how to run your application, it's time to instrument it. In the terminal windows that are running your application and simulator, press
<CTRL-C> to shut them down. With your app shut down, you'll be able to update your code to introduce monitoring tools.
This procedure is part of a lab that teaches you how to troubleshoot your web app with New Relic browser. Now that you've set up your environment, instrument your application with browser agent.
