A JupyterLab extension that integrates Language Server Protocol servers to bring IDE-like coding assistance to notebooks and files. It provides autocompletion, hover tooltips, diagnostics, jump-to-definition, and rename support across many languages.
Use cases
- get IDE-style autocompletion in JupyterLab notebooks
- jump to function definitions in a Jupyter notebook
- see linter diagnostics and errors inline while coding in JupyterLab
- hover over code to view function signatures and documentation
- rename variables safely across a notebook
- use language servers for Python, R, Julia, or TypeScript in JupyterLab
When to choose
- you use JupyterLab and want richer code intelligence than the built-in completer
- you work with notebooks in multiple languages and want consistent LSP features
- you need jump-to-definition and reference highlighting in notebook code
When to avoid
- you use classic Jupyter Notebook instead of JupyterLab
- you need a full standalone IDE rather than notebook-based editing
- your language has no available language server
