Discovering changes in content using Draft.JS: the ultimate guide

One event that I'm working with is the onChange, however, it triggers even when the cursor moves or navigation buttons are pressed.

I am looking to specifically identify if the content has been altered. Essentially, I only want to detect this once when the initial change occurs. Using the simplistic method of "comparing content" might solve this issue, but it's considered an anti-pattern due to its high resource consumption.

Answer №1

When Draft utilizes an immutable data structure, it does not require excessive resources – simply comparing references should suffice:

onUpdate(newEditorState) {
  const currentContent = this.state.editorState.getCurrentContent()
  const newContent = newEditorState.getCurrentContent()

  if (currentContent !== newContent) {
    // Content has been updated
  }
}
