Cannot find type definition file for 'jquery'

[gib96]

Hello,

I'm getting an error in Visual Studio 2015 when I try to compile my WebAPI project:

"Cannot find type definition file for 'jquery'"

I'm setting up my project using node.js.

The main folder for the project is RiskAlive9, and under that folder is a set of sub-projects:

-Core
-Database
-Test
-Web
-WebAPI

Everything compiles properly except for WebAPI which is giving me the error above.

Here's how I installed node, bower, and typescript:

npm install

This created a node_modules folder in the main folder (RiskAlive9).

npm install -g bower

This installed bower, gulp, and a bunch of pluggins for gulp.

bower install

This created a bower_components folder in the main folder (RiskAlive9).

npm install [email protected]

This installed typescript 2.4.1

npm install "@types/jquery"

This created a @types folder in the node_modules folder with a jquery folder inside it.

Yet WebAPI is still saying it cannot find the type definition file for jquery.

So I tried copying node_modules into the WebAPI folder. This fixed 99% of the errors (cannot find type definition file was not the only one), but also brought up a few new errors.

I'm wondering: does installing node typically mean installing it for every project in your solution (such that each sub-folder that needs to use node will have a node_modules folder)? Or isn't there a way to get all projects in your solution to use the main node_modules folder?

Check you typeSources array in tsconfig.json, makes ure it's either not defined, or includes node_modules/@types

Here is my tfconfig.json file:

{
"compilerOptions": {
"baseUrl": "./src",
"noEmitOnError": true,
"noImplicitAny": true,
"outDir": "./scripts/bowtie",
"outFile": "./scripts/bowtie/bowtie.js",
"sourceMap": false,
"declaration": false,
"target": "es5",
"typeRoots": [
"node_modules/@types"
],
"types": [
"jquery",
"d3"
]
},
"exclude": [
"obj",
"node_modules",
"WebAPI/node_modules",
"scripts/bowtie",
"../node_modules/"
],
"compileOnSave": true
}

Doesn't have typeSources at all.

It's in the WebAPI folder. Is this the right place for it?

If I were to let typeSources be undefined, would this be the right way to do it:

{
"compilerOptions": {
"baseUrl": "./src",
"noEmitOnError": true,
"noImplicitAny": true,
"outDir": "./scripts/bowtie",
"outFile": "./scripts/bowtie/bowtie.js",
"sourceMap": false,
"declaration": false,
"target": "es5",
"typeRoots": [
"node_modules/@types"
],
"types": [
"jquery",
"d3"
]
},
"typeSources": "undefined",
"exclude": [
"obj",
"node_modules",
"WebAPI/node_modules",
"scripts/bowtie",
"../node_modules/"
],
"compileOnSave": true
}

If I were to add "@types/jquery" to the file, would this be the right way to do it?

{
"compilerOptions": {
"baseUrl": "./src",
"noEmitOnError": true,
"noImplicitAny": true,
"outDir": "./scripts/bowtie",
"outFile": "./scripts/bowtie/bowtie.js",
"sourceMap": false,
"declaration": false,
"target": "es5",
"typeRoots": [
"node_modules/@types"
],
"types": [
"jquery",
"d3"
]
},
"typeSources": ["node_modules/@types"],
"exclude": [
"obj",
"node_modules",
"WebAPI/node_modules",
"scripts/bowtie",
"../node_modules/"
],
"compileOnSave": true
}

Thanks for helping out even though this isn't the right forum for this kind of question. Ironically, stackoverflow is NOT a better place for this kind of question because no one ever replies even when I'm perfectly on topic.

Do you know any forums specific to node?

@gib96 I meant typeRoots, and by making it undefined, I didn't mean setting it to the string "undefined", I meant not defining it at all.
