[TypeScript] Missing typedef error

[sinedied]

When using the SDK in a TypeScript project, you get this error unless you set "skipLibCheck": true in your tsconfig.json file:

../../node_modules/@github/copilot-sdk/dist/session.d.ts:5:40 - error TS2307: Cannot find module 'vscode-jsonrpc/node' or its corresponding type declarations.

5 import type { MessageConnection } from "vscode-jsonrpc/node";
                                         ~~~~~~~~~~~~~~~~~~~~~


Found 1 error in ../../node_modules/@github/copilot-sdk/dist/session.d.ts:5

Seems like a type export is missing.

Thank you for reporting this issue! I've labeled it as a bug for the sdk/nodejs implementation.

The issue is clear: the Node.js SDK's TypeScript definitions are missing the vscode-jsonrpc type declarations as a dependency, causing type errors unless skipLibCheck is enabled. This should be addressed by ensuring the package properly declares vscode-jsonrpc in its dependencies or devDependencies.

@sinedied can you share more about your setup? The vscode-jsonrpc library bundles its types and is listed as a dependency to the node SDK.

@friggeri Setup is pretty minimal: followed the quickstart, then added TS and @types/node with tsconfig.json:

npm install -D typescript @types/node

{
  "compilerOptions": {
    "target": "esnext",
    "module": "nodenext",
    "moduleResolution": "nodenext",
    "lib": ["esnext"],
    "strict": true,
  }
}

The running npx tsc triggers the error.

The vscode-jsonrpc lib is present:

✘  ~/projects/_test/copilot-sdk  npm ls vscode-jsonrpc
copilot-sdk@1.0.0 /Users/sinedied/projects/_test/copilot-sdk
