What is @types/codemirror?
@types/codemirror provides TypeScript type definitions for the CodeMirror library, which is a versatile text editor implemented in JavaScript for the browser. These type definitions help developers use CodeMirror in TypeScript projects by providing type safety and autocompletion features.
What are @types/codemirror's main functionalities?
Basic Initialization
This feature allows you to initialize a basic CodeMirror editor instance with some initial content and a specified mode (e.g., JavaScript).
const editor: CodeMirror.Editor = CodeMirror(document.body, { value: 'Hello, CodeMirror!', mode: 'javascript' });
Adding and Removing Line Widgets
This feature demonstrates how to add and remove line widgets in the CodeMirror editor. Line widgets are custom DOM elements that can be attached to specific lines in the editor.
const widgetNode = document.createElement('div');
widgetNode.innerText = 'This is a widget';
const lineWidget = editor.addLineWidget(1, widgetNode);
lineWidget.clear();
Handling Events
This feature shows how to handle events in the CodeMirror editor. In this example, an event listener is added to handle changes in the editor's content.
editor.on('change', (instance, changeObj) => {
console.log('Editor content changed:', changeObj);
});
Custom Key Bindings
This feature allows you to define custom key bindings for the CodeMirror editor. In this example, pressing 'Ctrl-S' will trigger a save command.
editor.setOption('extraKeys', {
'Ctrl-S': () => { console.log('Save command triggered'); }
});
