Question 1

How do I add a custom button for inserting images in react-native-markdown-editor?

Accepted Answer

Extend the Formats array with a new object that defines a key, wrapper (e.g., '![]()'), and onPress function using helper methods like applyWebLinkFormat or a custom handler. You'll need to handle image uploads separately, as the library focuses on markdown syntax insertion.

Question 2

react-native-markdown-editor vs react-native-markdown-view: which one should I use?

Accepted Answer

Use react-native-markdown-editor if you need an editing component with a toolbar and live preview. Choose react-native-markdown-view only for rendering markdown display without editing capabilities. This library builds on top of react-native-markdown-view for the preview feature.

Question 3

Can I use react-native-markdown-editor with Expo?

Accepted Answer

Yes, it should work with Expo's managed workflow since it's a pure JavaScript library. However, ensure compatibility with any native dependencies from react-native-markdown-view, though the README doesn't specify issues.

Question 4

How to hide the toolbar buttons in react-native-markdown-editor?

Accepted Answer

Pass an empty array to the Formats prop to disable all buttons, or customize the markdownButton rendering function to conditionally show/hide elements. The preview can be toggled separately using the showPreview prop.

Question 5

Is react-native-markdown-editor accessible for screen readers?

Accepted Answer

The README doesn't mention accessibility features, so you may need to add ARIA labels or custom rendering to ensure compliance. This oversight could require extra work for inclusive app development.

Question 6

How to handle large markdown documents without performance lag?

Accepted Answer

Optimize by throttling the onMarkdownChange callback or conditionally rendering the preview. The live preview relies on react-native-markdown-view, which may slow down with extensive content, so consider implementing virtualized lists or pagination.
