I am using Visual Studio Code (VSC) 0.10.11 on Windows and Mac. For the purpose of this question I have this small JavaScript snippet:
'use strict'; const os = require('os'); console.log(os.homedir());
I followed John Papa on Visual Studio Code (Blog entry and Pluralsight Visual Studio Code JavaScript Intellisense - for those who have an account) and therefore I would expect that VSC provides Intellisense and Quick fix options when typings are available.
In the snippet above VSC recognizes console
and log()
(I use hoover, but it is the same with Intellisense):
but not os
and homedir()
:
But all 4 typings are available in typings/main/ambient/node/index.d.ts
. I know that the difference is the require
in the case of os
, but in John Papa's video course VSC also provided IntelliSense for required modules. A difference is that John Papa used tsd
while I am using typings
.
So my questions are
Why is VS Code suggestions not working? If you're coding in JavaScript or TypeScript and finds that VSCode IntelliSense does work but does not behave properly, it's likely that you've selected the wrong language mode. TypeScript and JavaScript share the same language service, so you need to select the right language.
JavaScript in Visual Studio Code. Visual Studio Code includes built-in JavaScript IntelliSense, debugging, formatting, code navigation, refactorings, and many other advanced language features. Most of these features just work out of the box, while some may require basic configuration to get the best experience.
To access this options page, choose Tools > Options, and then choose Text Editor > C# > IntelliSense.
The above links are outdated. In older versions of VS Code you needed to reference your typings like /// <reference path> for somelibrary.d.ts
.
With new version you need to initialize your project by creating jsconfig.json
at the root of your project and add the following inside:
{ "compilerOptions": { "target": "es5", "module": "commonjs" }, "exclude": [ "node_modules" ] }
Next install typing you need. You can use either tsd or typings. In your case you need to install tsd install node
or typings install node --ambient
. Make sure you have typings/tsd
installed. Restart project.
Please refer to docs:
Update:
Since version 1.7 there is no need to manually install typings, they should be downloaded automatically. Better JavaScript IntelliSense
There is a built-in extension called TypeScript and JavaScript Language Features (vscode.typescript-language-features) that is disabled.
In order to enable it, open Extensions panel, search for "@built-in JavaScript", and enable the required extension.
Now you should be able to use the autocomplete feature.
