Issue tracking

Local server

The local server lets you to run the editor and serve the documentation from your own computer.

Setup

The following commands perform a one-time setup after synching the repo on your machine.

• install node.js 8.9.4 or higher
• install the PXT command line (add sudo for Mac/Linux shells).

npm install -g pxt

• install the microbit target

pxt target microbit

Running

Run this command to open a local web server (add sudo for Mac/Linux shells)

pxt serve

If the local server opens in the wrong browser, make sure to copy the URL containing the local token. Otherwise, the editor will not be able to load the projects.

The server assumes you have yotta installed. You can skip that requirement by adding --cloud.

pxt serve --cloud

Updates

To update your PXT version and make sure you're running the latest tools, run (add sudo for Mac/Linux shells):

pxt update
