Typescript: TS Server not picking up new TS files in vscode on MacOS

[mjbvz]

TypeScript Version: 3.7.0-dev.20190922

Search Terms:

• create-react-app

• tsconfig

Repo

1. npx create-react-app my-app --typescript
2. Open my-app in VS Code
3. Open app.tsx
4. Now create a new file next to it called add.ts with the content:

```ts
export function add() {}
```

1. Run the go to project configuration command in VS Code with add.ts open:

   • 🐛 Says it's not part of any configured project

2. Now go back to App.tsx and try using completions to add an auto import for add

   • 🐛 Auto import never works (unless you add an import manually)

Here are the logs:

This repos for me with 3.6.3 and for very simple projects like the following:

tsconfig.js

{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es2016",
        "jsx": "react"
    }
}

src/main.ts

export function foo() {
    add
}

src/add.ts (must be newly created)

export function add() { }

I don't know why we haven't seen this reported on the VS Code side (to my knowledge) but this bug is really annoying. @RyanCavanaugh @sheetalkamat I think this is worth at least investigating for a 3.6.x recovery

@mjbvz in the logs you showed there is only updateOpen but directory watcher for wild card directories is never invoked and that's the reason project doesn't know about app.tsx being part of it..

Info 80   [11:20:43.245] request:
    {"seq":14,"type":"request","command":"updateOpen","arguments":{"changedFiles":[],"closedFiles":[],"openFiles":[{"file":"/Users/matb/projects/san/sub/my-app/src/add.ts","fileContent":"","scriptKindName":"TS","projectRootPath":"/Users/matb/projects/san/sub/my-app"}]}}

When I repro your scenario (simple one) I don't see that behavior...

This was with the latest VS Code 1.39 insiders for me with MacOS 10.14.6. I've been able to repo the create-react-app issues it on two macs. Let me give it a quick try on my windows vm too

[mjbvz]

Seems to work ok on windows using create-react-app

This could be related to our electron update (which goes from node 10.11 to node 12.4). I can't seem to repo with the current stable VS Code builds using typescript@next

It definitely happens pretty consistently on mac VS Code insiders for me though. @RyanCavanaugh We need to investigate this before VS Code 1.39 ships

edit

The bug also repos using TS 3.5.3 so it does look more like an environment issue.

Possibly relevant: https://github.com/nodejs/node/issues/29460 . We should be able to confirm/disprove this theory by running the same version of TS Server on MacOS using node 10.11 and Node 12.4 and seeing if the behavior is different

[mjbvz]

We have reverted our Electron update for this release as this bug also effects other extensions

Closing this TS side issue in favor of the VS Code issue: https://github.com/microsoft/vscode/issues/81516

This is still an issue for me, running the latest stable VSCode version. @mjbvz was there any regressions since it was fixed in electron 6?

@danilofuchs Please open a new issue
