Language Servers#

Follow the setup steps for a language server to get it up and running.

If you encounter problems, consult the common issues page or search the LSP issues before opening new ones.

If there are no setup steps for a language server on this page, but a language server implementation exist, follow the guide for creating a client configuration. Pull requests for adding a new client configuration are welcome.

We recommend installing LSP-json.

LSP-json provides completions and diagnostics when editing JSON files that adhere to a JSON schema.
