TimelineJS3 is a JavaScript library for creating interactive storytelling timelines that can be embedded in web pages.
The tool addresses the need for non-technical users to construct visually rich timelines without coding knowledge. It works by allowing users to author timelines through an official web-based authoring tool, then embed them into websites using generated HTML snippets. The library supports multiple media types and can be configured through Google Sheets or JSON files, making it accessible to users with varying technical skill levels. For developers, the tool can be instantiated directly in a page rather than used as an iframe embed, with configuration options and a JavaScript API available for customization.
TimelineJS3 suits projects where storytelling through chronological visualization is central to the narrative. The official authoring tool handles most use cases for general audiences. Developers integrating timelines into existing websites can choose between the simple embed approach or direct instantiation with programmatic control. The project provides plugins for WordPress, MediaWiki, and Drupal to streamline embedding within those platforms. Those needing to work with the source code or customize behavior beyond configuration options will find the repository documentation and API reference on GitHub.
The project maintains active engagement with its community through a dedicated contributing guide. Development activity shows consistent attention to both the core library and its integration ecosystem across multiple content management systems.
