After you have installed the editor on the web or desktop app, it will automatically sync to your mobile app after you sign in.


Prerequisites: Install Node.js, Yarn, and Git on your computer.

The general instructions setting up an environment to develop Standard Notes extensions can be found here. You can also follow these instructions:

  1. Fork the repository on GitHub.
  2. Clone your fork of the repository.
  3. Run cd music-editor to enter the music-editor directory.
  4. Run yarn install to install the dependencies on your machine as they are described in yarn.lock.

Testing in the browser#

  1. To run the app in development mode, run yarn start and visit http://localhost:3001. Press ctrl/cmd + C to exit development mode.

Testing in the Standard Notes app#

  1. Create an ext.json in the public directory. You have three options:
    1. Use sample.ext.json.
    2. Create ext.json as a copy of sample.ext.json.
    3. Follow the instructions here with url: "http://localhost:3000/index.html".
  2. Install http-server using sudo npm install -g http-server then run yarn server to serve the ./build directory at http://localhost:3000.
  3. To build the app, run yarn build.
  4. Install the editor into the web or desktop app with http://localhost:3000/sample.ext.json or with your custom ext.json. Press ctrl/cmd + C to shut down the server.


  1. To make the source code prettier, run yarn pretty.
  2. To the deploy the build into the gh-pages branch of your repository on GitHub, run yarn deploy-stable.
  3. To deploy the build into to the dev branch for testing, run yarn deploy-dev.
  4. To deploy the built into the build branch for distributing, run yarn deploy-build for distributing builds.

This project was bootstrapped with Create React App.

Available Scripts#

In the project directory, you can run:

yarn start#

Runs the app in the development mode.\ Open http://localhost:3001 to view it in the browser.

The page will reload if you make edits.\ You will also see any lint errors in the console.

yarn test#

Launches the test runner in the interactive watch mode.\ See the section about running tests for more information.

yarn build#

Builds the app for production to the build folder.\ It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.\ Your app is ready to be deployed!

See the section about deployment for more information.

yarn eject#

Note: this is a one-way operation. Once you eject, you can't go back!

If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.

You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
