    Sir Trevor

    Build Status

    Conceived by Andrew Sprinz. Maintained by Chris Bell & Andrew Walker.

    Upgrade guide from v0.5

    Quick start

    The recomended way to install Sir Trevor in your project is using npm. This will install all the files required in the build directory for the module.

    npm install sir-trevor

    Note: Sir Trevor is distributed combined with its dependencies. If you wish to modify Sir Trevor you will want to clone the repository and use the Compiling instructions below.


    <form><textarea class="js-st-instance"></textarea></form>


    import SirTrevor from "sir-trevor";
    const editor = new SirTrevor.Editor({
      el: document.querySelector(".js-st-instance"),
      defaultType: "Text",
      iconUrl: "build/sir-trevor-icons.svg"

    Custom blocks

    We are keeping a list of custom block repos here. See the documentation to find out more about adding your own block types.

    Browser support

    Sir Trevor is only tested on the following modern browsers:

    ECMAScript 6 shims are bundled in by default; if the platform you wish to run on doesn't support ECMAScript 5 APIs you'll need to shim those yourself.

    Sir Trevor uses The Guardian's scribe for rich text editing. Double check their browser support if your application relies on full RTE support.


    See the roadmap and read a little about the philosophy guiding development.

    Customising the way it looks

    We use Sass for our styles, if you'd like to change the default styling please fork the repository and make changes to the Sass before recompiling.

    Customising blocks

    Block Types can also easily be added to the SirTrevor.Blocks object. You can also override the default block types (Text, Image, Tweet, Video, Quote, Heading & List) at any time. See the documentation to find out more about adding your own block types.


    Tests are run as part of compilation process, which require chromedriver to be installed on the machine where you are running the compilation. If you're running Homebrew on OSX this can be installed via brew install chromedriver.

    Before getting started please be sure to install the necessary dependencies via npm:

    $ npm install

    When completed, we have a couple of preset scripts:

    $ npm run dev

    This compiles for development, and watches source files to recompile when you change something.

    $ npm test

    Runs the linter and test suite, just like the CI server does.

    $ npm run dist

    Concatenates scripts, compiles the Sass, runs the Jasmine tests and minifies the project.

    Please ensure any pull requests have relevant Jasmine tests (where applicable).
