Question

When using the node runtime with TypeScript is there some special handling concerning the TypeScript compiler flags e g `noImplicitAny` I m using some third party javascript library which doesn t provide good type definitions and as I m only using two methods I went with a custom `thelib d ts` file containing `declare module thelib ` This works with `noImplicitAny` in my IDE and on the command line but fails when it is handed over to the pulumi runtime Not sure if this a Pulumi issue as I would somehow also expect it to fail locally i added my d ts file to the files array and the typeRoots in tsconfig

What error do you get You should be able to set compilation flags in `tsconfig json` We just load `ts node` into the Node process to compile on module load ` ts` files It should be reading the `tsconfig json` to decide what TypeScript compilation flags to pass

Error is TS7016 Could not find a declaration file for module mssql

rhythmic-finland-36256 · Answer

works when I do `npx tsc p tsconfig json`

And to validate it fails when I remove the content of the `mssql d ts` file and issue the same `tsc` command

tsconfig ``` compileOnSave true compilerOptions strict true outDir bin target es2016 module commonjs moduleResolution node sourceMap true experimentalDecorators true pretty true noFallthroughCasesInSwitch true noImplicitReturns true forceConsistentCasingInFileNames true typeRoots node modules types typings mssql d ts files index ts dummy ts typings mssql d ts mssql tasks ts mssql serviceuser ts ```

Still wondering if a simple `declare module mssql ` should work if I m using `noImplicitAny` as I m somehow not defining the types explicitly

There are also a bunch of typescript github issues related to that topic of `noImplicitAny` and those simple declarations <https github com Microsoft TypeScript issues 15031>

The long version of the error is ```TSError Unable to compile TypeScript mssql tasks ts 1 22 error TS7016 Could not find a declaration file for module mssql Users ajaegle dev evals pulumi tests testing dynamic provider node modules mssql index js implicitly has an any type Try `npm install types mssql` if it exists or add a new declaration d ts file containing `declare module mssql ```

It looks like something weird when passing the ts d ts files to the runtime and then resulting in the noImplicitAny problem as the module was not declared anywhere

Let me check this one <https github com TypeStrong ts node help my types are missing>

rhythmic-finland-36256 · Answer

All right I somehow screwed up the `typeRoots` which must point to a directory similar to `node modules types`

rhythmic-finland-36256 · Answer

With the correct folder structure of the typings folder `typings lt module name gt lt jsfilename gt d ts` and the following `typeRoots` it works ``` typeRoots node modules types typings ```

What s the best place to add this to the docs Is there some JS TS specific documentation
