JavaScript/TypeScript language server
This is a language server for JavaScript and TypeScript that adheres to the Language Server Protocol (LSP). It uses TypeScript's LanguageService to perform source code analysis.
Try it out
- On sourcegraph.com
- In Visual Studio Code (as an alternative to the built-in TypeScript integration)
- In Eclipse Che
- In NeoVim
- In Sublime Text
Features
- Hovers
- Goto definition
- Goto type definition
- Find all references
- Document symbols
- Workspace symbol search
- Rename
- Completion
- Signature help
- Diagnostics
- Quick fixes
Run it from source
1# install dependencies 2npm install 3 4# compile 5npm run build 6# or compile on file changes 7npm run watch 8 9# run over STDIO 10node lib/language-server-stdio 11# or run over TCP 12node lib/language-server 13 14# run tests 15npm test
Options
Usage: language-server [options]
Options:
-h, --help output usage information
-V, --version output the version number
-s, --strict enabled strict mode
-p, --port [port] specifies LSP port to use (2089)
-c, --cluster [num] number of concurrent cluster workers (defaults to number of CPUs, 8)
-t, --trace print all requests and responses
-l, --logfile [file] log to this file
-j, --enable-jaeger enable OpenTracing through Jaeger
Extensions
This language server implements some LSP extensions, prefixed with an x.
- Files extension Allows the server to request file contents without accessing the file system
- SymbolDescriptor extension Get a SymbolDescriptor for a symbol, search the workspace for symbols or references to it
- Streaming Supports streaming partial results for all endpoints through JSON Patches
- Packages extension Methods to get information about dependencies
- TCP / multiple client support
When running over TCP, the
exitnotification will not kill the process, but close the TCP socket
Versioning
This project follows semver for command line arguments and standard LSP methods. Any change to command line arguments, Node version or protocol breaking changes will result in a major version increase.
Debugging Performance with OpenTracing
The language server is fully traced through OpenTracing, which allows to debug what exact operations caused method calls to take long.
You can pass a span context through an optional meta field on the JSON RPC message object.
For local development, there is built-in support for the open source OpenTracing implementation Jaeger, which can be set up to run on localhost with just one command (you need Docker installed):
docker run -d -p5775:5775/udp -p6831:6831/udp -p6832:6832/udp \
-p5778:5778 -p16686:16686 -p14268:14268 jaegertracing/all-in-one:latest
After that, run the language server with the --enable-jaeger command line flag and do some requests from your client.
Open http://localhost:16686 in your browser and you will see method calls broken down into spans.
