16n editor

The 16n editor allows you to edit the configuration of your 16n from within a web browser. It supports 16ns running firmware 2.0.0 and up.

The 16n editor is a Javascript app based around Svelte.

Build Requirements

• Node.js v8+

Usage Requirements

• As a WebMIDI app, you need a client that can support it. That basically means Chrome right now.
• A 16n running firmware v2.0.0 or higher.

Installation

npm install

Running the development environment

npm run dev

This will run a development environment at localhost:5000, with live reloading enabled.

By default, the server will only respond to requests from localhost.

Building and running in production mode

To create an optimised version of the app:

npm run build

You can run the newly built app with npm run start. This uses sirv, which is included in your package.json's dependencies so that the app will work when you deploy to platforms like Heroku.

Code formatting

We use prettier for code formatting. From your local directory:

npx prettier --write 'src'

will prettify the src/ directory. Code that fails Prettier's formatting standards will block merge at Github.

We're using a similar approach to the one Simon Willison describves here.

Project Structure

• src/App.Svelte is quite dense, but is the main entrypoint for the application and contains the app's structure.
• src/components contains all components. Primarily UI, but MidiContext serves to wrap WebMidi and keep the various stores that describe the available Midi interfaces up-to-date.
• src/Configuration.js describes a class ConfigurationObject, that represents a single instance of a 16n configuration. These are what are passed around, diffed to work out if config has changed, and converted to Sysex to send to the device.
• src/ImportExport.js handles converting a Configuration to JSON, and back again.
• src/OxionMidi.js is some convenience classes for MIDI.

Deployment

The built site is committed to a subdirectory on the 16n site, for now.
