Obsidian Zotero Bridge Plugin

Obsidian-Zotero integration plugin that provides APIs for other plugins to connect to Zotero.

Prerequisites

Zotero <= 6

Install Zotero addon ZotServer

Configuration

The plugin settings screen provides the following options:

• Connection type – Zotero 6 ZotServer Plugin or Zotero 7 Local API (v3)
• User or group – which library to search: your personal library or one of your group libraries (Zotero 7 connection type only)
• Zotero server port – defaults to 23119; don't change unless you really know what you are doing

How to use

Zotero Bridge provides APIs for other plugins to connect to Zotero.

Example of such consumer plugin is Zotero Link.

APIs of this plugin are published with Obsidian plugin api library and can be used anywhere in Obsidian.

PluginApi.ZoteroBridge.v1().search() opens a search modal and returns a promise that resolves with the selected ZoteroItem. Its getValues() method returns an object with the following properties, ready for use in templates:

• key – Zotero item key
• libraryUri – library path for zotero:// URIs: groups/<id> for group library items, library for the personal library
• title – item title
• shortTitle – item short title
• date – structured date object with year, month and day properties
• authors – array of authors, each with firstName, lastName and fullName
• firstAuthor – first author of the item
• creatorSummary – creator summary as displayed by Zotero, e.g. "Smith and Jones"

Example use of Zotero Bridge APIs in Templater user scripts:

zotero.js user script:

module.exports = async function () {
    const item = await PluginApi.ZoteroBridge.v1().search();
    return (prop) => dotAccess(prop, item.getValues());
}

function dotAccess(str, obj) {
    return str.split('.').reduce((previousValue, currentValue) => previousValue[currentValue], obj);
}

This function can now be used in templates:

(this example is taken from https://github.com/vanakat/zotero-bridge/pull/2)

<%* const zi = await tp.user.zotero() %>


<% zi('firstAuthor.lastName') %><%* if (zi('authors.length')  == 2) { %> and <% zi('authors')[1].lastName %><%* } else if (zi('authors.length') > 2) { %> et al.<%* } %> <% zi('date.year') %> <% zi('title') %>
