🙁 Actual behavior

I have installed both TypeScript 6 and 7 side to side following the blog post.
Unfortunately, typescript-language-server (which is a LSP wrapper around tsserver from TypeScript 6) does not work in this setup. It is looking for a tsserver.js file in node_modules/typescript/lib, which does not exist in @typescript/typescript6.

🙂 Expected behavior

The @typescript/typescript6 package is for compatibility with software based on TypeScript 6, so it should include a tsserver.js executable. I believe the only thing needed is to add a tsserver.js file in the lib directory containing:

require("@typescript/old/lib/tsserver.js");

(same pattern as the existing tsc.js file)
I tested it and typescript-language-server does start when adding this file.

Additional information about the issue

I know that TypeScript 7 includes a new native LSP server, but it does not have all the features that tsserver had. In particular the lack of code actions like "Move to file" make it so that I want to be able to switch between the old and the new server until the new server reaches feature parity.

Bắt đầu trong thư mục lib của gói tương thích @typescript/typescript6 và so sánh wrapper tsc.js hiện có với entry point tsserver.js còn thiếu. Thêm entry point tương thích tsserver.js tương ứng và xác minh rằng typescript-language-server khởi động với gói này.
