This recipe will show you how we can use the WebREPL CLI to transfer files from a computer to the ESP8266 over Wi-Fi. This is a very powerful way of transferring files to the board. Each time you make changes to your Python code and want to try the latest change, you have to upload the file to the board. Doing this with your web browser over and over again can become tedious.
The beauty of using the CLI interface is that most Terminals remember their last executed commands, so you can rerun the last command with two simple keystrokes: you just press the up arrow key and the Enter key. This will make your cycle of code, upload, and run much faster and more productive.
