Solid Calendar Store

This library allows users to perform a list of calendar operations via the Community Solid Server (CSS). This is achieved by offering stores and converters for CSS. For an overview of all possible transformations and conversions see the documentation.

How to run

  1. Install dependencies via npm i.
  2. Navigate to examples via cd examples.
  3. Rename examples/config-example.json to examples/config.json.
  4. Update examples/config.json.
  5. Run server via npx community-solid-server -c config.json -m ...

See the Community Solid Server documentation for more information on what each parameter does.

Note that the latest version of the RMLMapper is downloaded when you first run the server. You have the option to provide a custom version by putting it in the project and calling it rmlmapper.jar.


  1. Make sure you have the required packages to support typescript compiling installed on your machine.
  2. Run the server via npx to ensure you are running local packages as opposed to global packages.
  3. You can use Google Calendars via two methods:
    1. Using a private URL for your Google Calendar combined with the HTTP Get Store.
    2. Using the Google Calendar Get Store config/config-calendar.json
      1. Update calendar id of Google Calendar in config/config-calendar.json.
      2. Give Solid Calendar Store access to Google Calendar API via
        node scripts/get-google-access-token.js`


These endpoints are the default provided ones. See config/config-calendar.json to see how they are set up and how you can customize them.

Availability Store

You find an example of the settings for this store in /examples/availability-store-settings.yaml. In this file, you define the availability slots via availabilitySlots and the minimum duration in minutes of a single slot via minimumSlotDuration.

Transformation Store

You find an example of the settings for this store in /examples/transformation-store-settings.yaml. In this file, you define all rules via transformation. Each rule is of the following format:

  match: [regex]
  replace: [string]
  removeFields: [string array]
  • name is the name of the rules and does not have to be unique. For example, it is possible to define multiple rules with the name "busy" and let them all be applied when navigating to /busy.
  • match should be a valid JavaScript regex, excluding the //. It is important that when regex characters are escaped, e.g. \*, you place the match text in '' and not "".
  • replace is the string that will replace all the matched parts.
  • removeFields is an optional string array that defines the to-be-removed fields of an event. If you do not provide this attribute, then only the title, start date and end date are kept.

Holiday Store

You find an example of the settings for this store in /examples/holiday-store-settings.yaml. You can define 3 types of holidays:

  • constant: Holidays that are always on the same day (example: New Year)
  • shifting: Holidays that fall on the nth day of a month (example: Mothers Day)
  • fluid: Holidays that are not exactly possible to be strictly defined (example: Easter)

You structure them in a JSON file like this:

  - name: [holiday name]
      day: [UTC day]
      month: [UTC month]
  - name: [holiday name]
      n: [the nth it falls on]
      weekday: [which UTC weekday]
      month: [UTC month]
  [holiday name]: [date (incl. year)]

See docs/ for places where you can use the holidays.

Calendar JSON format used by the stores

For the calendar name the X-WR-CALNAME field is used.
Not all possible event fields of an ICS calendar are used. You find the used field in src/event.ts.
