An intelligent TypeScript editor that highlights all compilation errors across the entire project, not just within currently open files

After experimenting with various development environments including Eclipse with Codemix plugin, Palantir TS plugin, and Wild Web Developer plugin, as well as VisualStudio Code, I found that they only display errors on open files. Is there an IDE available that can show compilation errors across all the files in a project?

Additionally, I'm curious to know why this feature is not standard for TypeScript compared to other languages like Java in IDEs. Any insights on this bonus question?

Answer №1

It appears that all IDEs only display errors for open files. Is there a tool available that can show compilation errors for all files in a project?

If you configure a watch task in VSCode, it can accomplish this.

Setting up a watch task

In your package.json, add the following scripts:

"scripts": {
    "watch": "tsc --watch --noEmit --project './tsconfig.json'"
  },

Configure the file .vscode/tasks.json:

{
  "version": "2.0.0",
  "tasks": [
    {
      "type": "npm",
      "script": "watch",
      "problemMatcher": "$tsc-watch",
      "isBackground": true,
      "presentation": {
        "reveal": "always",
        "revealProblems": "onProblem"
      }
    }
  ]
}

To run the watch task in vscode command palette, go to Tasks: Run Task and select npm: watch
