NotePlan Plugins

Each plugin command can be invoked using the NotePlan Command Bar, or by entering any of available commands directly in the editor by entering / (NotePlan will auto update the list of possible commands as you type)

Anatomy of a Plugin

If you want to develop plugins, Step 1 is to read the NotePlan Knowledgebase Document describing how plugins work in NotePlan and the basic plugin anatomy. Once you have read that carefully and understand the basics, you should return here to acquire and start using the NotePlan Plugin tooling described below.

Prerequisite

The following items are required for NotePlan Plugin Development

• Node 14 or 16 -- Do Not Use any Node version <14 or >16 (see "Switching Node Versions")
• NotePlan 3.4 or greater
• macOS Catalina 10.15.2 or greater (strongly recommend macOS Big Sur 11.x or Monterey 12.x)
• github CLI gh is strongly recommended - how to install gh

Switching Node Versions

The NotePlan plugin code has not yet been migrated to Node versions >16. If you are developing elsewhere using Node v17+, you will want to switch to Node v16 when you are doing NotePlan Plugin development. The fast/easy way to do that is with a Node version manager like "n". This way you can flip in and out of Node versions at will.

Plugin Information

If you have an idea for a plugin, submit them here or inquire in the NotePlan Discord community's #plugin channel.

If you are a developer and want to contribute and build your plugins, see the plugin writing documentation and discuss this with other developers on Discord #plugin-dev channel. You might want to consult this good modern JavaScript tutorial.

Getting Started with Plugin Development

Step 1: Forking/Cloning NotePlan Plugin Repository

Read these instructions for how to fork and clone this code

Step 1.5 Have a look at the code

When you have cloned this repository, you will not only have the tooling, but you will have the actual source code for every publicly-available NotePlan plugin. This will give you a wealth of material to learn from and borrow from. Speaking of which, there is a /helpers directory at the root of the repository that contains a lot of useful functions built upon the NotePlan APIs and will speed up your development. It would be good to familiarize yourself with that code by browsing it. There is a searchable index of the helper code that can be accessed by running this command in a terminal: npm run docs

Step 2: Install Node (if not installed)

Make sure you have the proper version of node installed (if you need to install node, brew install node@16 is the quickest method, or you can follow instructions on node website).

Step 3: Initialize Local Development Environment

Run the following 2 commands from the root of your local GitHub repository for NotePlan/plugins.

1) Install the node_modules

npm install

2) Link the files to make them run properly from the command line (especially the noteplan-cli)

npm run init

This will install the necessary npm dependencies and initialize your plugin working directory, including:

• Configuring eslint eslint (for checking code conventions)
• Configuring flow flow (for type checking)
• Configuring babel babel (a JS compiler)
• Configuring rollup rollup (for bundling multiple source files into a single release).

_Note: Each of these configuration files can be overridden if needed by placing a project specific configuration file in you project plugin, however, for consistency with other NotePlan plugins, we encourage to use the defaults wherever possible._

Creating your first NotePlan Plugin

Using the NotePlan CLI, perform the following actions:

Step 1: Create your plugin using NotePlan CLI Answer the prompt questions (or supply all the necessary options from command line (see noteplan-cli plugin:create --help for details)

noteplan-cli plugin:create

Step 2: Startup Auto Watch Process

Open up a Terminal shell, cd to the repository root directory, and issue the command: npc plugin:dev --watch from the root directory to build your plugin as you develop so it can be tested in NotePlan. This will compile your code and put it into your NotePlan app directory so you can test your plugin. The --watch flag keeps the process looking for changes to your files and will automatically rebuild the plugin for you. (more on that below)

Step 3: Start your plugin command develop and test locally

You can now develop and test your plugin locally,

Step 4: Create Pull Request (if you wish to make your plugin public)

At this point, if you would like to make your plugin available publicly, you can proceed to creating a Pull Request to have your code included in the NotePlan Plugin Repository

Common Development Actions

These are the most common commands you will use while developing:

File Watcher

The default watch command npc plugin:dev --watch:

npc plugin:dev from the root of your local NotePlan/plugins repository which will bundle all the files in your /src directory into single file script.js and will be copied from your repository directory to your Plugins folder in the running NotePlan data directory for testing.

The init script should have detected whether you are using the SetApp or App Store version of NotePlan and set the correct path to your Plugins folder. If it did not, you can manually change it in .pluginpath.

Note: The watcher will remain running, _watching_ the NotePlan directory and re-compile whenever changes have been made to your /src JavaScript files.

npc plugin:dev --watch

For example, running npc plugin:dev dwertheimer.TaskAutomations --watch will perform the same watching operations for the dwertheimer.TaskAutomations plugin only.

NotePlan CLI Commands

NotePlan includes a suite of CLI commands which you can use during development.

noteplan-cli <command>
or
npc <command>

For all CLI commands, you can pass the --help for available flags

npc plugin:dev

The most common CLI command, this can be used to build plugin, test plugins (wrapper for npc plugin:test)

npc plugin:dev <plugin> [options]
run watcher, compact mode and display notification with build result
npc plugin:dev codedungeon.Toolbox --watch --compact --notify
same as above, using CLI shorthand
npc plugin:dev codedungeon.Toolbox -wcn
run NotePlan test suite in watch mode
this is a wrapper for npc plugin:test
npc plugin:dev codedungeon.Toolbox -tw

npc plugin:test

The test command can be used in addition to the npc plugin:dev --test which will only execute the NotePlan Test Runner

npc plugin:test <plugin> [options]
execute test running in watch mode, with silent enabled
npc plugin:test codedungeon.Toolbox --watch --silent
as with other plugin commands, youc an use CLI shorthand
this will perform the same as above
npc plugin:test codedungeon.Toolbox -ws

npc plugin:create

Create new NotePlan Plugin

npc plugin:create [options]

npc plugin:pr

Create NotePlan Plugin Pull Request

npc plugin:pr [options]

npc plugin:test

Run test suite for NotePlan Plugin

npc plugin:test <plugin> [options]
run plugin:test watch
npc plugin:test codedungeon.Toolbox --watch
run plugin:test watch, silent mode
npc plugin:test codedungeon.Toolbox --watch --silent
run plugin:test with CLI shorthand
npc plugin:test codedungeon.Toolbox -ws
run plugin:test with coverage report
npc plugin:test codedungeon.Toolbox --coverage

Create Pull Request

Once you are finished editing and testing your plugin, you can submit a Pull Request to the NotePlan/plugins repository and it will be reviewed for inclusion. Once it has been approved, it will be available from NotePlan > Preferences > Plugins section, enabling it to be installed by other NotePlan users.

Frequently Used Commands

The common script you will run npc plugin:dev however, you may need to use any of the following

• npc plugin:dev --watch --compact --notify a less verbose version of autowatch that might suit more experienced developers
• npc plugin:dev -wcn watcher, compact mode, notify using CLI shorthand
• npc plugin:dev -tw test mode, watcher using CLI shorthand
• npc plugin:test -w test mode, using test command
• npm run typecheck: typecheck all javascript files with Flow. Only files with a // @flow comment are checked.
• npm run fix: lint and auto-format
• npm run docs: build documentation for javascript files
• npm run lint: run ESlint on the entire repo
• npm run lint-fix: run ESlint on the entire repo and fix whatever it can automatically fix
• npm run format: auto-format all Javascript files using prettier
• gh release delete : Will delete the release from the repository, so making it unavailable in NotePlan as well. (Though it won't remove it from anyone who has already downloaded it.)

Viewing Plugin Logs

Everything your plugin (or its WebView) logs goes into NotePlan's rolling log file. nplog is a terminal viewer for it — it follows the newest log file across NotePlan restarts, filters live by regex as you type, and keeps pretty-printed objects together as a single entry instead of scattering them across lines.

./scripts/nplog/install.sh   # one-time; symlinks nplog onto your PATH
nplog                        # follow the log
nplog 'ERROR|WARN'           # start with a filter set (though you can change it at any time)

For scripts, CI, or an AI agent debugging a plugin, --json turns the same parser into a one-shot command that emits NDJSON and exits 1 if anything errored:

CURSOR=$(nplog --mark)
open "noteplan://x-callback-url/runPlugin?pluginID=jgclark.Dashboard&command=Show%20Dashboard"
nplog --since "$CURSOR" --follow --wait-idle 5 --json   # stream what that action logged

AI agents working in this repo get this automatically as a Claude Code skill, committed at .claude/skills/nplog/SKILL.md. That is a hidden directory, so ls and Finder won't show it — but it ships with the clone and needs no installation.

See scripts/nplog/README.md for the key bindings, headless options, and how to make the skill available outside this repo.

Editor Setup

Use the setup guide for your preferred editor (we prefer Visual Studio Code), and then read the section on Working with Multiple Files.

Visual Studio Code (recommended)

Install VSCode Extensions

1. Install the following extensions for the following tools:

Update Settings

1. Set prettier to be the default formatter for js files.

1. Restart the editor to ensure the plugins are working.

1. Make sure to open this folder directly in VSCode and not the entire repo as the ESLint plugin can be annoying about that

Sublime Text 3 and 4

1. Install the following extensions using Package Control

1. Configure your packages:

Linting Code

If you don't have an editor set up to lint as you code, you can run npm run test and it will give a list of problems to fix.

Using Flow

By practice, NotePlan plugins use flow for static type checking. You can get more information by referencing NotePlan Flow Guide
