Build Status

An element with CodeMirror editor to allow the user to enter HTTP message body.

Breaking Changes in v3

  1. Upgrade

The element now uses LitElement library instead of Polymer. This means that all attributes are lowercase without - characters. For example, previously the lineSeparator property was reflected to line-separator attribute. Now it is lineseparator attribute.

  1. Tab handling

CodeMirror traps focus in the editor area. This is not accessible way of handling user input. Because of that this element overrides default tab key behavior and removes focus from the element.

  1. Required imports

This version uses latest and final specs for web components. This means the component works as a ES module. Because of that CodeMirror and any related library has to be included into the document before inserting this element to the DOM. CodeMirror 6 possibly will be working with ES imports but this is not set in stone at the moment.

Below is the default set of scripts to be added to the document.

<script src="node_modules/codemirror/lib/codemirror.js"></script>
<script src="node_modules/codemirror/addon/mode/loadmode.js"></script>
<script src="node_modules/codemirror/mode/meta.js"></script>
<!--Default set of parsers -->
<script src="node_modules/codemirror/mode/javascript/javascript.js"></script>
<script src="node_modules/codemirror/mode/xml/xml.js"></script>
<script src="node_modules/codemirror/mode/htmlmixed/htmlmixed.js"></script>

If you are using JSON linter

<script src="node_modules/jsonlint/lib/jsonlint.js"></script>
<script src="node_modules/codemirror/addon/lint/lint.js"></script>
<script src="node_modules/codemirror/addon/lint/json-lint.js"></script>
<link rel="stylesheet" href="node_modules/codemirror/addon/lint/lint.css" />

Finally, if your application will use modes that aren't included in the document, you should set import URI. This will be used to resolve modes dependencies.

CodeMirror.modeURL = 'node_modules/codemirror/mode/%N/%N.js';
