Advanced: Using a bundler

For apps using a bundler, install using NPM and then import into your app.

npm install --save tangy-form-editor

import `tangy-form-editor/tangy-form-editor.js`

You have to copy an ace build to your root directory in order to get syntax highlighting. In an angular-cli project (as of Angular 4) you can do this by adding the following assets entry to your apps build target.

  { "glob": "**/*", "input": "../node_modules/ace-builds/src-noconflict/", "output": "./" },

        <template>
          <tangy-input name="text_input_1" label="This is an input for text." type="text"></tangy-input>
        </template>
      </tangy-form-item>
      <tangy-form-item id="text_inputs_2" title="Text Inputs 2">
        <template>
          <tangy-input name="text_input_2" label="This is an input for text that is required." type="text" error-message="This is required." required></tangy-input>
        </template>

Browser Compatibility

The combination of CKEditor breaking when used in Shadow DOM and Firefox / IE shadow DOM support is still behind a flag, this means this element does not currently work in Firefox and IE.

Support for translations

Follow the instructions for the tangy-translate library to enable translated or alternate labels.
