Usage
Adding the dependencies
There are two options for adding StoriiiesViewer to your project:
In the browser
(This is the quickest and easiest way to get started)
You can include the JavaScript and CSS in the HTML like so, using the unpkg CDN:
<head>
<!-- ... -->
<link rel="stylesheet" href="https://unpkg.com/@cogapp/storiiies-viewer@latest/dist/storiiies-viewer.css">
<script src="https://unpkg.com/@cogapp/storiiies-viewer@latest/dist/umd/storiiies-viewer.js"></script>
<!-- ... -->
</head>Or you could save these files and serve them locally if you prefer.
Including the JavaScript file this way will make StoriiiesViewer available globally in JavaScript.
Using a bundler
- Install the dependecy with
npm install @cogapp/storiiies-viewer - Use
import StoriiiesViewer from '@cogapp/storiiies-viewer'in your code to access the StoriiiesViewer constructor - Depending on how your tooling handles importing CSS you might also be able to import the CSS file with
import @cogapp/storiiies-viewer/dist/storiiies-viewer.css— but you could also use the method above, or copy the contents of the CSS file into your own src files.
Initialise a viewer
In your HTML:
<div id="storiiies-viewer"></div>In your JavaScript
document.addEventListener('DOMContentLoaded', () => {
const myViewer = new StoriiiesViewer({
container: "#storiiies-viewer", // or document.querySelector("#storiiies-viewer")
manifestUrl: "https://path-to-your-storiiies-manifest",
});
});Customisation
To customise of appearance of StoriiiesViewer you have a few options:
- If you'd prefer to bring all your own styles, StoriiiesViewer can be styled from scratch without needing to include the default stylesheet
- To 'theme' StoriiiesViewer, you may find the custom properties provided by the default stylesheet to be sufficient
- Start with default stylesheet and expand or override these styles as you see fit
Supported manifest formats
StoriiiesViewer supports a subset of the IIIF presentation API v3. Specifically, we target annotationPages which are included directly in the manifest (like in this cookbook recipe).
Annotations themselves can either be text/plain or text/html denoted by the format field. For text/plain newline characters will be converted and output as <br> tags.
StoriiiesViewer has no required fields (aside from those required by the presentation API), but it will render certain values from the manifest if provided. These are:
- A manifest
label, which is required by the presentation API and will be shown on a "title slide", before any annotations - A manifest level
summary, which will appear below the label if provided - A manifest level
requiredStatement, which will appear below the summary if provided
!NOTE Certain features which aren't currently supported include:
- Externally referenced
annotationPages(as shown in this cookbook recipe)- Multiple images
- Non-text based annotations (e.g. audio)
- Full multi-lingual support
However, pathways exist to enable these features with further development.
!WARNING Manifest with a version lower than 3 may load images, but aren't guaranteed to work beyond this, and will display a warning in the console.
Compatibility with Storiiies Editor
Cogapp maintains a free-to-use editor for Storiiies at storiiies-editor.cogapp.com. To use a compatible v3 manifest for your story, append the short alphanumeric code from the "view and share" link to a base URL of https://manifest.storiiies-editor.cogapp.com/v3/
For example, for the link https://storiiies.cogapp.com/viewer/7e4va/A-Sunday-on-La-Grande-Jatte-1884 use a manifest URL of https://manifest.storiiies-editor.cogapp.com/v3/7e4va
Local development
Installation
Pre-requisites
!IMPORTANT Although optional, we recommend using nvm to match the version of Node used in this project before running the install command, or the npm scripts described below.
If you encounter problems and aren't using the version of Node shown in the .nvmrc file, you should try aligning your node version to this first. This represents a known compatibility with the code here and our dependencies.
Setup
Switch node version and install the dependencies in the project root with:
nvm use
npm ciCompiling and previewing changes
Running the tests
!NOTE
npm run cypress:guiandnpm run cypresswill also do the same as the above without starting the dev server, if you already have it running.
