Local server

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


This section explains how to setup your development environment for pxt-microbit, whether that be to run a copy locally or to make source changes.
Note that pxt-microbit can not be run without its main depandancy, pxt. Below explains how to setup both.

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

  • Note for any editing of the .cpp files, Yotta must be installed. Do do so, follow the instructions on their site.
  • Install node.js 8.9.4 or higher.
  • Install requirements for pxt. Note the v0 branch must be used for pxt-microbit (add sudo for Mac/Linux shells).
npm install -g jake
npm install -g typings
git clone https://github.com/microsoft/pxt
cd pxt
git checkout v0
  • Install the pxt dependencies.
npm install
typings install
cd ../
git clone https://github.com/microsoft/pxt-microbit
cd pxt-microbit
  • install the PXT command line (add sudo for Mac/Linux shells).
npm install -g pxt
  • install the dependencies
npm install

  • Link pxt-microbit back to base pxt repo.
npm link ../pxt

Note the above command assumes the folder structure of

  |               |
 pxt        pxt-microbit


Run this command from inside pxt-microbit to open a local web server (add sudo for Mac/Linux shells)

pxt serve --cloud

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.

If you need modify the .cpp files (and have installed yotta), enable yotta compilation by removing the --cloud flag (add sudo for Mac/Linux shells):

pxt serve


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

pxt update
