Zeus IDE

npm install -g typescript-language-server

With the software installed test the installation by running typescript-language-server.cmd -h at the command line prompt, which should result in the following output:

Usage: typescript-language-server [options]

Options:
  -V, --version                                    output the version number
  --stdio                                          use stdio
  --log-level <logLevel>                           A number indicating the log level (4 = log, 3 = info, 2 = warn, 1 =
                                                   error). Defaults to `2`.
  --tsserver-log-verbosity <tsserverLogVerbosity>  [deprecated] Specify a tsserver log verbosity (terse, normal,
                                                   verbose). Defaults to `normal`. example: --tsserver-log-verbosity
                                                   verbose
  --tsserver-path <path>                           [deprecated] Specify path to tsserver.js or the lib directory.
                                                   example: --tsserver-path=/Users/me/typescript/lib/tsserver.js
  -h, --help                                       display help for command
        

If that output is not produced check the installation and also check to make sure the batch file installation folder has been added to the system PATH environment variable.

NOTE: Some of those options have been [deprecated] and these should not be used.

Start Zeus and use the Options, Document Types menu to edit the TypeScript document type and in the Language Server panel apply the following configuration settings:

Program Type: Batch
     Program: typescript-language-server.cmd
   Directory:
   Arguments: --stdio
              --log-level=4
              --tsserver-log-verbosity=verbose
        

NOTE: The directory value is only required if the location of the typescript-language-server.cmd file has not been added to the system PATH.

To test the configuration create a simple test.ts file and fire off an auto-complete request:

This short video shows the autocomplete in action.

The TypeScript language server can also work with a package.json project file but the language server will need to located that file. The easiest way to achieve this is to create a Zeus workspace in that project folder location and then leave the Root Path language server option empty. With that setup in place Zeus will automatically set the Root Path to match the location of the currently open workspace.
