Ketcher is an open-source web-based chemical structure editor incorporating high performance, good portability, light weight, and ability to easily integrate into a custom web-application. Ketcher is designed for chemists, laboratory scientists and technicians who draw structures and reactions.

For more details please look at the following link.

The ketcher-react package contains only the functionality necessary to define components. It is used together with ketcher-core and optionally with ketcher-standalone if standaolone mode is required.

Installation

The ketcher-react library is available as an NPM package. Install it either with NPM:

npm install --save ketcher-react

or Yarn:

yarn add ketcher-react

Usage

import { RemoteStructServiceProvider } from 'ketcher-core'

const structServiceProvider = new RemoteStructServiceProvider(
  process.env.REACT_APP_API_PATH!,
  {
    'custom header': 'value' // optionally you can add custom headers object 
  }
)

const MyComponent = () => {
  return (
    <Editor
      staticResourcesUrl={process.env.PUBLIC_URL}
      structServiceProvider={structServiceProvider}
    />
  )
}

Indigo Service

Ketcher uses Indigo Service for server operations. You may pass it as a property while Editor component is used or just add api_path query parameter:

<Editor staticResourcesUrl={process.env.PUBLIC_URL} apiPath={link to Indigo service} />
    or
http://localhost:3000/?api_path={link to Indigo service}

You can find the instruction for service installation here.

3D Viewer

Ketcher uses Miew-React for viewing and editing data in 3D. Miew-React package default exports Viewer component which initializes and renders a Miew instance inside of it

...
import Viewer from 'miew-react'

const MyComponent = () => {
  return <Viewer />
}
...
...
