For Mirador Users

You can quickly use and configure Mirador by remixing the mirador-start Glitch.

We recommend installing Mirador using a JavaScript package manager like npm or yarn.

$ npm install mirador 

# or

$ yarn add mirador

If you are interested in integrating Mirador with plugins into your project, we recommend using webpack or parcel to integrate the es version of the packages. Examples are here:

https://github.com/ProjectMirador/mirador-integration

If you want to simply embed Mirador in an HTML page without further customization, include the Mirador UMD build:

<script src="https://unpkg.com/mirador@latest/dist/mirador.min.js"></script>

More examples of embedding Mirador can be found at https://github.com/ProjectMirador/mirador/wiki/M3-Embedding-in-Another-Environment#in-an-html-document-with-javascript.

Adding translations to Mirador

For help with adding a translation, see src/locales/README.md

Running Mirador locally for development

Mirador local development requires nodejs to be installed.

  1. Run npm install to install the dependencies.

Starting the project

$ npm start

Then navigate to http://127.0.0.1:4444/

Instantiating Mirador

var miradorInstance = Mirador.viewer({
  id: 'mirador' // id selector where Mirador should be instantiated
});

> miradorInstance
{ actions, store }

Example Action

Add a window:

store.dispatch(actions.addWindow());

To focus a window run:

store.dispatch(actions.focusWindow('window-1'))

Check current state

store.getState()

Running the tests

We use Vitest to run our test suite.

$ npm test

You can see the helpful Vitest UI in your browser by running Vitest with the --ui flag. To pass the flag through to npm run the following:

$ npm test -- --ui

You can run Vitest without the additional linting and size checks in our npm test command. You can also test a single file:

$ npx vitest __tests__/integration/mirador/tests/sequence-switching.test.js --ui

Linting the project

$ npm run lint

Debugging

Local instance

The following browser extensions are useful for debugging a local development instance of Mirador:

Test suite

To debug the test suite, run:

$ npm run test:debug

then spin up a nodejs inspector client and set some breakpoints. See here for a guide to debugging with Chrome DevTools.
