VSCode TypeScript lint

Question

People, who develop TypeScript used Visual Studio Code? I'm trying to use it too. But I have no validation(ts-lint) warnings or errors. I just got such messages on build:

ts-lint start
src/constants/type.ts[22, 2]: file should end with a newline
src/constants/type.ts[6, 5]: misplaced opening brace
ts-lint end

Example:

1 == 2

Such expression in JS file will message me that it will be better to use 1 === 2 . But this expression in TS file will work and not even show any warning.

What can I do to enable such validation in TypeScript, while typing?

Answer 1

Just had the exact same problem and seem to have resolved by adding "typescript" to the eslint.validate array in workspace settings

{
 "eslint.validate": [
    "javascript",
    "javascriptreact",
    "typescript"
    ]
}

Should you be new to VSCode. F1 => type "settings" => from the dropdown select either "user settings" (any project for that logged in user) or "workspace settings" (that one project only) => paste the above object on the right pane (or extend the existing object should there be one)

Answer 2

Please update to 0.8.0 version of vs code, just released. JavaScript Linting as you Type is now supported. https://code.visualstudio.com/updates

Answer 3

I did some experimentation running into a similar problem and found that I had a jsconfig.json file laying around that was created prior to converting code over to TypeScript. After removing/renaming that file and restarting VSCode it appears that my TypeScript compiler errors are now showing up as the error output when doing a build in VSCode as opposed to seemingly unrelated errors about unresolved imports.

I'm not sure if this is the same problem you're experiencing but hopefully it's of some help to you or somebody else.
