codemirror-svelte

Provides a CodeMirror wrapper component for Svelte.

The current library supports CodeMirror 6. If you want to use CodeMirror 5, install version 1.2.1.

In CodeMirror 6, it has been modularized. This library was intended to be a thin wrapper, so perhaps it is not needed. If you want a high-level library with abstraction, there is svelte-codemirror-editor.

Installation

npm install -D codemirror-svelte

Usage

Check the CodeMirror Reference Manual.

<!-- Foo.svelte -->
<script lang="ts">
  import Codemirror, { basicSetup } from "codemirror-svelte";

  import { EditorView } from "@codemirror/view";

  import { markdown, markdownLanguage } from "@codemirror/lang-markdown";
  import { languages } from "@codemirror/language-data";

  import { oneDarkTheme } from "@codemirror/theme-one-dark";

  // initial content
  let doc = "";

  const extensions = [
    basicSetup,
    markdown({ base: markdownLanguage, codeLanguages: languages }),
    oneDarkTheme,
    EditorView.theme({
      "&": {
        height: "800px",
        fontSize: "20px"
      }
      // ..
    })
    // ..
  ];
</script>

// ..
<Codemirror {doc} {extensions} />
