Features

❗The localization system is upgraded (dtd is deprecated and we do not use .properties anymore). Only supports Zotero 7.0.0-beta.12 or higher now. If you want to support Zotero 6, you may need to use dtd, properties, and ftl at the same time. See the staled branch zotero6-bootstrap.

Event-driven, functional programming, under extensive skeleton;
Simple and user-friendly, works out-of-the-box.
⭐[New!]Auto hot reload! Whenever the source code is modified, automatically compile and reload. See here→
Abundant examples in src/modules/examples.ts, covering most of the commonly used APIs in plugins(using zotero-plugin-toolkit);
TypeScript support:
- Full type definition support for the whole Zotero project, which is written in JavaScript(using zotero-types);
- Global variables and environment setup;
Plugin build/test/release workflow:
- Automatically generate/update plugin id/version, update configrations, and set environment variables(development/production);
- Automatically build and reload code in Zotero;
- Automatically release to GitHub(using release-it);

Quick Start Guide

Install Pre-built `xpi`

See how the examples work by directly downloading the xpi file from GitHub release and install it to your Zotero.

This is also how your plugin will be released and used by others.

The release do not promise any real functions. It is probably not up-to-date.

The xpi package is a zip file. However, please don't modify it directly. Modify the source code and build it.

Build from Source

Fork this repo/Click Use this template;
Git clone the forked repo;
Enter the repo folder;
Modify the settings in ./package.json, including:

{
  version,
  author,
  description,
  homepage,
  config {
    releasepage, // URL to releases(`.xpi`)
    updaterdf, // URL to update.json
    addonName, // name to be displayed in the plugin manager
    addonID, // ID to avoid confliction. IMPORTANT!
    addonRef, // e.g. Element ID prefix
    addonInstance // the plugin's root instance: Zotero.${addonInstance}
  }
}

Be careful to set the addonID and addonRef to avoid confliction.

Run npm install to set up the plugin and install dependencies. If you don't have NodeJS installed, please download it here;
Run npm run build to build the plugin in production mode. Run npm run build-dev to build the plugin in development mode. The xpi for installation and the built code is under builds folder.

What the difference between dev & prod?

This environment variable is stored in Zotero.${addonInstance}.data.env. The outputs to console is disabled in prod mode.

You can decide what users cannot see/use based on this variable.

Release

To build and release, use

# A release-it command: version increase, npm run build, git push, and GitHub release
# You need to set the environment variable GITHUB_TOKEN https://github.com/settings/tokens
# release-it: https://github.com/release-it/release-it
npm run release

Setup Development Environment

Install a beta version of Zotero: https://www.zotero.org/support/beta_builds (Zotero 7 beta: https://www.zotero.org/support/dev/zotero_7_for_developers)
Install Firefox 102(for Zotero 7)
Copy zotero command line config file. Modify the commands that starts your installation of the beta Zotero.

(Optional) Do this only once: Start the beta Zotero with /path/to/zotero -p. Create a new profile and use it as your development profile. Use /path/to/zotero -p {profile_name} to specify which profile to run with.

cp ./scripts/zotero-cmd-default.json ./scripts/zotero-cmd.json
vim ./scripts/zotero-cmd.json

Setup plugin development environment following this link.
Build plugin and restart Zotero with npm run restart.
Launch Firefox 102(Zotero 7)
In Firefox, go to devtools, go to settings, click "enable remote debugging" and the one next to it that's also about debugging

Enter about:debugging#/setup in FF 102.

In Zotero, go to setting, advanced, config editor, look up "debugging" and click on "allow remote debugging".
Connect to Zotero in Firefox. In FF 102, enter localhost:6100 in the bottom input of remote-debugging page and click add.
Click connect in the leftside-bar of Firefox remote-debugging page.
Click "Inspect Main Process"

Auto Hot Reload

Tired of endless restarting? Forget about it!

Run npm run start-watch. (If Zotero is already running, use npm run watch)
Coding. (Yes, that's all)

When file changes are detected in src or addon, the plugin will be automatically compiled and reloaded.

💡 Steps to add this feature to an existing plugin

Copy scripts/reload.mjs
Copy reload, watch, and start-watch commands in package.json
Run npm install --save-dev chokidar-cli
Done.

Debug in Zotero

You can also:

Test code snipastes in Tools->Developer->Run Javascript;
Debug output with Zotero.debug(). Find the outputs in Help->Debug Output Logging->View Output;
Debug UI. Zotero is built on the Firefox XUL framework. Debug XUL UI with software like XUL Explorer.

XUL Documentation: http://www.devdoc.net/web/developer.mozilla.org/en-US/docs/XUL.html

About Hooks

See also src/hooks.ts

When install/enable/startup triggered from Zotero, bootstrap.js > startup is called
- Wait for Zotero ready
- Load index.js (the main entrance of plugin code, built from index.ts)
- Register resources if Zotero 7+
In the main entrance index.js, the plugin object is injected under Zotero and hooks.ts > onStartup is called.
- Initialize anything you want, including notify listeners, preference panes, and UI elements.
When uninstall/disabled triggered from Zotero, bootstrap.js > shutdown is called.
- events.ts > onShutdown is called. Remove UI elements, preference panes, or anything created by the plugin.
- Remove scripts and release resources.

About Global Variables

See also src/index.ts

The bootstrapped plugin runs in a sandbox, which does not have default global variables like Zotero or window, which we used to have in the overlay plugins' window environment.

This template registers the following variables to the global scope:

Zotero, ZoteroPane, Zotero_Tabs, window, document, rootURI, ztoolkit, addon;

Create Elements API

The plugin template provides new APIs for bootstrap plugins. We have two reasons to use these APIs, instead of the createElement/createElementNS:

In bootstrap mode, plugins have to clean up all UI elements on exit (disable or uninstall), which is very annoying. Using the createElement, the plugin template will maintain these elements. Just unregisterAll at the exit.
Zotero 7 requires createElement()/createElementNS() → createXULElement() for remaining XUL elements, while Zotero 6 doesn't support createXULElement. The React.createElement-like API createElement detects namespace(xul/html/svg) and creates elements automatically, with the return element in the corresponding TS element type.

createElement(document, "div"); // returns HTMLDivElement
createElement(document, "hbox"); // returns XUL.Box
createElement(document, "button", { namespace: "xul" }); // manually set namespace. returns XUL.Button

About Build

Use Esbuild to build .ts source code to .js.

Use replace-in-file to replace keywords and configurations defined in package.json in non-build files (.xul/xhtml, .dtd, and .properties).

Steps in scripts/build.js:

Clean ./builds
Copy ./addon to ./builds
Esbuild to ./builds/addon/chrome/content/scripts
Replace __buildVersion__ and __buildTime__ in ./builds/addon
Zip the ./builds/addon to ./builds/*.xpi

About Zotero API

Zotero docs are outdated and incomplete. Clone https://github.com/zotero/zotero and search the keyword globally.

⭐The zotero-types provides most frequently used Zotero APIs. It's included in this template by default. Your IDE would provide hint for most of the APIs.

A trick for finding the API you want:

Search the UI label in .xul(.xhtml)/.dtd/.properties files, find the corresponding key in locale file. Then search this keys in .js/.jsx files.

Directory Structure

This section shows the directory structure of a template.

All .js/.ts code files are in ./src;
Addon config files: ./addon/chrome.manifest, ./addon/install.rdf, and ./addon/manifest.json;
UI files: ./addon/chrome/content/*.xhtml.
Locale files: ./addon/chrome/locale/[*.dtd, *.properties];
Resource files: ./addon/chrome/skin/default/__addonRef__/*.dtd;
Preferences file: ./addon/chrome/defaults/preferences/defaults.js;

Don't break the lines in the defaults.js
