Heyho,
I want to use some javascript libraries in my typescript code for which there are no typings in npm. So I wrote the typings myself and put them in a definitions
directory in my source tree. However, I could not get typescript to look in that directory for those modules.
My directory structure looks like this:
+-node_modules
| |
| +-moduleA
| |
| +-moduleB
|
+-src
| |
| +-definitions
| | |
| | +-moduleA.d.ts
| | |
| | +-moduleB.d.ts
| |
| +-ts
| |
| + ... all typescript code ...
|
+-tsconfig.json
I tried including the modules in the definitions
-directory using
include
files
typeRoots
paths
However none of it worked.
Can somebody tell me, how to get typescript to include those typings?
PS: Why is the TypeScript module handling so complicated???
TypeScript automatically finds type definitions under node_modules/@types , so there's no other step needed to get these types available in your program.
This @types scoped package is where we can find a ton of useful type definitions, such as for example the type definitions of node that allow us to use require for example.
{
"compilerOptions": {
"typeRoots": [
"./node_modules/@types",
"./some-custom-lib"
]
}
}
the typeRoots string array is just for that. In addition to your regular "node_modules/@type", add a custom made typings folder.
