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,
    updaterdf,
    addonName,
    addonID,
    addonRef
  }

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.AddonTemplate.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

1. 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)

2. Install Firefox 60(for Zotero 6)/Firefox 102(for Zotero 7)

3. 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

4. Setup plugin development environment following this link.

5. Build plugin and restart Zotero with npm run restart.

6. Launch Firefox 60(Zotero 6)/Firefox 102(Zotero 7)

7. In Firefox, go to devtools, go to settings, click "enable remote debugging" and the one next to it that's also about debugging

Press shift+F8 in FF 60, or enter about:debugging#/setup in FF 102.

8. In Zotero, go to setting, advanced, config editor, look up "debugging" and click on "allow remote debugging".

9. Connect to Zotero in Firefox.

In FF 60, click the hamburger menu in the top right -> web developer -> Connect..., then enter localhost:6100.

In FF 102, enter localhost:6100 in the bottom input of remote-debugging page and click add.

10. Click connect in the leftside-bar of Firefox remote-debugging page.

11. Click "Inspect Main Process"

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

1. 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+
2. 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.
3. 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;

About Preference

Zotero 6 doesn't support preference pane injection in bootstrap mode, thus I write a register for Zotero 6 or lower.

You only need to maintain one preferences.xhtml which runs natively on Zotero 7 and let the plugin template handle it when it is running on Zotero 6.

Zotero 7

Zotero 6

08d72a4e2b/src/modules/examples.ts (L73-L85)

<preferences> element is deprecated. Please use the full pref-key in the elements' preference attribute. Like:

<checkbox label="&zotero.__addonRef__.pref.enable.label;" preference="extensions.zotero.__addonRef__.enable" />

The elements with preference attributes will bind to Zotero preferences.

Remember to call unregister() on plugin unload.

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:

1. Clean ./builds
2. Copy ./addon to ./builds
3. Esbuild to ./builds/addon/chrome/content/scripts
4. Replace __buildVersion__ and __buildTime__ in ./builds/addon
5. 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;
