React component wrapper for EasyMDE (the most fresh SimpleMDE fork).
Only two dependencies, React (peer) and EasyMDE (explicit).
simplemde
itself. Possible breaking changes, so I bumped version to v4.simplemde/dist/simplemde.min.css
now it will be easymde/dist/easymde.min.css
initialValue
prop has been removed and replaced with a value
prop, allowing direct changes to the value to be made after the component mounts.Version 1.0 did not have SimpleMDE options configured well, this readme reflects the changes made to better include options. This is still a very new project. Testing, feedback and PRs are welcome and appreciated.

or view it locally:
git clone https://github.com/RIP21/react-simplemde-editor.git
cd react-simplemde-editor
yarn install
yarn demo
open browser with localhost:3000
View the demo code for a full example.
Not required, but useless without it, the onChange
callback is the only option you need to set.
source-js
import React from "react";
import SimpleMDE from "react-simplemde-editor";
import "easymde/dist/easymde.min.css";
<SimpleMDE onChange={this.handleChange} />;
The data from SimpleMDE is passed to the handleChange function and you do not need to reference the event.
source-js
handleChange = value => {
this.setState({ mdeValue: value });
};
Set additional SimpleMDE options with an options prop.
Note - while SimpleMDE options has an initialValue
option, this component only takes a value
prop which is set as the initialValue
on first render.
Note - if you don’t specify a custom id it will automatically generate an id for you.
source-js
import React from "react";
import SimpleMDE from "react-simplemde-editor";
import "easymde/dist/easymde.min.css";
<SimpleMDE
id="your-custom-id"
label="Your label"
onChange={this.handleChange}
value={this.state.textValue}
options={{
autofocus: true,
spellChecker: false
// etc.
}}
/>;
You can include key maps using the extraKeys
prop. Read more at https://codemirror.net/doc/manual.html#option_extraKeys
source-js
extraKeys = {
Up: function(cm) {
cm.replaceSelection(" surprise. ");
},
Down: function(cm) {
cm.replaceSelection(" surprise again! ");
}
};
<SimpleMDE
value={this.state.textValue}
onChange={this.handleChange}
extraKeys={extraKeys}
/>;
source-js
import ReactDOMServer from "react-dom/server";
<SimpleMDE
value={this.state.text}
onChange={this.setText}
options={{
previewRender(text) {
return ReactDOMServer.renderToString(
<ReactMarkdown

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?
In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.
Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.
React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.
Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.
Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.
The popularity of React Native comes from its advantages. Some of its advantages are as follows:
Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.
React Native is very close to native. Consider the following aspects as described on the React Native website:
Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

Since March 2020 reached 556 million monthly downloads have increased, It shows that React JS has been steadily growing. React.js also provides a desirable amount of pliancy and efficiency for developing innovative solutions with interactive user interfaces. It’s no surprise that an increasing number of businesses are adopting this technology. How do you select and recruit React.js developers who will propel your project forward? How much does a React developer make? We’ll bring you here all the details you need.
Facebook built and maintains React.js, an open-source JavaScript library for designing development tools. React.js is used to create single-page applications (SPAs) that can be used in conjunction with React Native to develop native cross-platform apps.
In the United States, the average React developer salary is $94,205 a year, or $30-$48 per hour, This is one of the highest among JavaScript developers. The starting salary for junior React.js developers is $60,510 per year, rising to $112,480 for senior roles.
In context of software developer wage rates, the United States continues to lead. In high-tech cities like San Francisco and New York, average React developer salaries will hit $98K and $114per year, overall.
However, the need for React.js and React Native developer is outpacing local labour markets. As a result, many businesses have difficulty locating and recruiting them locally.
It’s no surprise that for US and European companies looking for professional and budget engineers, offshore regions like India are becoming especially interesting. This area has a large number of app development companies, a good rate with quality, and a good pool of React.js front-end developers.
As per Linkedin, the country’s IT industry employs over a million React specialists. Furthermore, for the same or less money than hiring a React.js programmer locally, you may recruit someone with much expertise and a broader technical stack.
React is a very strong framework. React.js makes use of a powerful synchronization method known as Virtual DOM, which compares the current page architecture to the expected page architecture and updates the appropriate components as long as the user input.
React is scalable. it utilises a single language, For server-client side, and mobile platform.
React is steady.React.js is completely adaptable, which means it seldom, if ever, updates the user interface. This enables legacy projects to be updated to the most new edition of React.js without having to change the codebase or make a few small changes.
React is adaptable. It can be conveniently paired with various state administrators (e.g., Redux, Flux, Alt or Reflux) and can be used to implement a number of architectural patterns.
Is there a market for React.js programmers?
The need for React.js developers is rising at an unparalleled rate. React.js is currently used by over one million websites around the world. React is used by Fortune 400+ businesses and popular companies such as Facebook, Twitter, Glassdoor and Cloudflare.
As you’ve seen, locating and Hire React js Developer and Hire React Native developer is a difficult challenge. You will have less challenges selecting the correct fit for your projects if you identify growing offshore locations (e.g. India) and take into consideration the details above.
If you want to make this process easier, You can visit our website for more, or else to write a email, we’ll help you to finding top rated React.js and React Native developers easier and with strives to create this operation

React component wrapper for EasyMDE (the most fresh SimpleMDE fork).
Only two dependencies, React (peer) and EasyMDE (peer).
Built by @RIP21 👨💻
Table of contents generated with markdown-toc
>=16.8.2
easymde
now a peer dependency, please install it manuallylabel
prop has been removedoptions
shall be memoized to prevent new instances from being created on each render and other related to that bugs (more on that below)ref
, so you can easily get access to div
wrapper by using ref
prop.@babel/runtime
helpers are no longer inlined but imported.npm install --save react-simplemde-editor easymde
Note: Possibly you may need to install @babel/runtime
, try without it, but if you don't have any issues, then you shouldn't.
or to see it locally:
git clone https://github.com/RIP21/react-simplemde-editor.git
cd react-simplemde-editor
yarn install
yarn demo
open browser at localhost:3000
View the demo code for more examples.
All examples below are in TypeScript
Uncontrolled usage
import React from "react";
import SimpleMDE from "react-simplemde-editor";
import "easymde/dist/easymde.min.css";
<SimpleMDE />;
export const ControlledUsage = () => {
const [value, setValue] = useState("Initial value");
const onChange = useCallback((value: string) => {
setValue(value);
}, []);
return <SimpleMdeReact value={value} onChange={onChange} />;
};
You can set API of SimpleMDE options which you pass down as a options
prop. If you're using TypeScript it will be inferred by compiler.
Note: if you don't specify a custom id it will automatically generate an id for you.
Note that you need to useMemo
to memoize options
so they do not change on each rerender! It will affect behavior and performance because then on each render of the parent that renders SimpleMdeReact
you'll get a new instance of the editor, which you definitely want to avoid! Also, if you change options
on each value
change you will lose focus. So, put options
as a const
outside of the component, or if options
shall be partially or fully set by props
make sure to useMemo
in case of functional/hooks components, or class field for class
based components. Slightly more on that here: #164
export const UsingOptions = () => {
const [value, setValue] = useState("Initial");
const onChange = useCallback((value: string) => {
setValue(value);
}, []);
const autofocusNoSpellcheckerOptions = useMemo(() => {
return {
autofocus: true,
spellChecker: false,
} as SimpleMDE.Options;
}, []);
return (
<SimpleMdeReact
options={autofocusNoSpellcheckerOptions}
value={value}
onChange={onChange}
/>
);
};
You can include key maps using the extraKeys
prop. Read more at CodeMirror extra keys
export const UpdateableByHotKeys = () => {
const extraKeys = useMemo<KeyMap>(() => {
return {
Up: function (cm) {
cm.replaceSelection(" surprise. ");
},
Down: function (cm) {
cm.replaceSelection(" surprise again! ");
},
};
}, []);
const [value, setValue] = useState("initial");
const onChange = (value: string) => setValue(value);
return (
<SimpleMdeReact value={value} onChange={onChange} extraKeys={extraKeys} />
);
};
import ReactDOMServer from "react-dom/server";
export const CustomPreview = () => {
const customRendererOptions = useMemo(() => {
return {
previewRender() {
return ReactDOMServer.renderToString(
<ReactMarkdown

Here is how you do it. It requires mock of certain browser pieces to work, but this is whole example.

return { right: 0 };
},

right: 0,
};
},
};
};
const Editor = () => {
const [value, setValue] = useState("");
return <SimpleMdeReact value={value} onChange={setValue} />;
};
describe("Renders", () => {
it("succesfully", async () => {
act(() => {
render(<Editor />);
});
const editor = await screen.findByRole("textbox");
userEvent.type(editor, "hello");
expect(screen.getByText("hello")).toBeDefined();
});
});

}
