This repository is a fork of SimpleMDE, made by Sparksuite. Go to the dedicated section for more information.
A drop-in JavaScript text area replacement for writing beautiful and understandable Markdown. EasyMDE allows users who may be less experienced with Markdown to use familiar toolbar buttons and shortcuts.
In addition, the syntax is rendered while editing to clearly show the expected result. Headings are larger, emphasized words are italicized, links are underlined, etc.
EasyMDE also features both built-in auto saving and spell checking. The editor is entirely customizable, from theming to toolbar buttons and javascript hooks.
Via npm:
npm install easymde --save
Via the UNPKG CDN:
<link rel="stylesheet" href="https://unpkg.com/easymde/dist/easymde.min.css">
<script src="https://unpkg.com/easymde/dist/easymde.min.js"></script>
After installing and/or importing the module, you can load EasyMDE onto the first TextArea on the web page:
<textarea></textarea>
<script>
var easyMDE = new EasyMDE();
</script>
Alternatively you can select a specific TextArea, via Javascript:
<textarea id="my-text-area"></textarea>
<script>
var easyMDE = new EasyMDE({element: document.getElementById('my-text-area')});
</script>
Or via jQuery:
<textarea id="my-text-area"></textarea>
<script>
var easyMDE = new EasyMDE({element: $('#my-text-area')[0]});
</script>
Use EasyMDE.value() to get the content of the editor:
<script>
easyMDE.value();
</script>
Use EasyMDE.value(val) to set the content of the editor:
<script>
easyMDE.value('New input for **EasyMDE**');
</script>

Below are the built-in toolbar icons (only some of which are enabled by default), which can be reorganized however you like. “Name” is the name of the icon, referenced in the JS. “Action” is either a function or a URL to open. “Class” is the class given to the icon. “Tooltip” is the small tooltip that appears via the title=""
attribute. Note that shortcut hints are added automatically and reflect the specified action if it has a key bind assigned to it (i.e. with the value of action
set to bold
and that of tooltip
set to Bold
, the final text the user will see would be “Bold (Ctrl-B)”).
Additionally, you can add a separator between any icons by adding "|"
to the toolbar array.
Name | Action | Tooltip Class |
---|---|---|
bold | toggleBold | Bold fa fa-bold |
italic | toggleItalic | Italic fa fa-italic |
strikethrough | toggleStrikethrough | Strikethrough fa fa-strikethrough |
heading | toggleHeadingSmaller | Heading fa fa-header |
heading-smaller | toggleHeadingSmaller | Smaller Heading fa fa-header |
heading-bigger | toggleHeadingBigger | Bigger Heading fa fa-lg fa-header |
heading-1 | toggleHeading1 | Big Heading fa fa-header header-1 |
heading-2 | toggleHeading2 | Medium Heading fa fa-header header-2 |

Customize the toolbar using the toolbar
option.
Only the order of existing buttons:
var easyMDE = new EasyMDE({
toolbar: ["bold", "italic", "heading", "|", "quote"]
});
All information and/or add your own icons
var easyMDE = new EasyMDE({
toolbar: [{
name: "bold",
action: EasyMDE.toggleBold,
className: "fa fa-bold",
title: "Bold",
},
{
name: "custom",
action: function customFunction(editor){
// Add your own code
},
className: "fa fa-star",
title: "Custom Button",
},
"|" // Separator
// [, ...]
]
});
EasyMDE comes with an array of predefined keyboard shortcuts, but they can be altered with a configuration option. The list of default ones is as follows:
Shortcut (Windows / Linux) | Shortcut (macOS) | Action |
---|---|---|
Ctrl-’ | Cmd-’ | “toggleBlockquote” |
Ctrl-B | Cmd-B | “toggleBold” |
Ctrl-E | Cmd-E | “cleanBlock” |
Ctrl-H | Cmd-H | “toggleHeadingSmaller” |
Ctrl-I | Cmd-I | “toggleItalic” |
Ctrl-K | Cmd-K | “drawLink” |
Ctrl-L | Cmd-L | “toggleUnorderedList” |
Ctrl-P | Cmd-P | “togglePreview” |
Ctrl-Alt-C | Cmd-Alt-C | “toggleCodeBlock” |
Ctrl-Alt-I | Cmd-Alt-I | “drawImage” |
Ctrl-Alt-L | Cmd-Alt-L | “toggleOrderedList” |
Shift-Ctrl-H | Shift-Cmd-H | “toggleHeadingBigger” |
F9 | F9 | “toggleSideBySide” |
F11 | F11 | “toggleFullScreen” |
Here is how you can change a few, while leaving others untouched:
var editor = new EasyMDE({
shortcuts: {
"toggleOrderedList": "Ctrl-Alt-K", // alter the shortcut for toggleOrderedList
"toggleCodeBlock": null, // unbind Ctrl-Alt-C
"drawTable": "Cmd-Alt-T", // bind Cmd-Alt-T to drawTable action, which doesn't come with a default shortcut
}
});
Shortcuts are automatically converted between platforms. If you define a shortcut as “Cmd-B”, on PC that shortcut will be changed to “Ctrl-B”. Conversely, a shortcut defined as “Ctrl-B” will become “Cmd-B” for Mac users.
The list of actions that can be bound is the same as the list of built-in actions available for toolbar buttons.
You can catch the following list of events: https://codemirror.net/doc/manual.html#events
var easyMDE = new EasyMDE();
easyMDE.codemirror.on("change", function(){
console.log(easyMDE.value());
});
You can revert to the initial text area by calling the toTextArea
method. Note that this clears up the autosave (if enabled) associated with it. The text area will retain any text from the destroyed EasyMDE instance.
var easyMDE = new EasyMDE();
// ...
easyMDE.toTextArea();
easyMDE = null;
The following self-explanatory methods may be of use while developing with EasyMDE.
var easyMDE = new EasyMDE();
easyMDE.isPreviewActive(); // returns boolean
easyMDE.isSideBySideActive(); // returns boolean
easyMDE.isFullscreenActive(); // returns boolean
easyMDE.clearAutosavedValue(); // no returned value
EasyMDE is a continuation of SimpleMDE.
SimpleMDE began as an improvement of lepture’s Editor project, but has now taken on an identity of its own. It is bundled with CodeMirror and depends on Font Awesome.
CodeMirror is the backbone of the project and parses much of the Markdown syntax as it’s being written. This allows us to add styles to the Markdown that’s being written. Additionally, a toolbar and status bar have been added to the top and bottom, respectively. Previews are rendered by Marked using GFM.
I originally made this fork to implement FontAwesome 5 compatibility into SimpleMDE. When that was done I submitted a pull request, which has not been accepted yet. This, and the project being inactive since May 2017, triggered me to make more changes and try to put new life into the project.
Changes include:
https://
by defaultMy intention is to continue development on this project, improving it and keeping it alive.
You may want to edit this library to adapt its behavior to your needs. This can be done in some quick steps:
gulp
command, which will generate files: dist/easymde.min.css
and dist/easymde.min.js
