Custom typings not working with ts-node 8.0.2

[p-kuen]

After updating to ts-node version 8.0.2 the custom typings (currently placed in ./types) don't work anymore.
When I am changing the version to 8.0.1 the typings are working fine.

Typescript version: 3.3.3

Current tsconfig.json:

{
 "compilerOptions": {
 "sourceMap": true, // allow sourcemap support
 "strictNullChecks": true, // enable strict null checks as a best practice
 "strict": true,
 "target": "esnext", // specify ECMAScript target version
 "module": "commonjs",
 "moduleResolution": "node",
 "noImplicitAny": true,
 "declaration": false,
 "typeRoots": ["./@types"],
 "emitDecoratorMetadata": true,
 "experimentalDecorators": true,
 "outDir": "./build"
 },
 "include": ["./src/", "./types"],
 "exclude": ["node_modules", ".logs", "upload"]
}

Error Message:

uncaughtException: ⨯ Unable to compile TypeScript:
src/import/law.ts(2,28): error TS7016: Could not find a declaration file for module 'csv-string'. '/home/patrick/dev/bodner-api/node_modules/csv-string/index.js' implicitly has an 'any' type.

This is expected behavior, have you read https://github.com/TypeStrong/ts-node#help-my-types-are-missing?

👍 for broken custom typings.
node-ts 8.0.1 have no such problem, also tsc doesn't see any problems with TS 3.3.3

My case:

start script at package.json:

"scripts": {
 "server-dev": "ts-node --project src/server/tsconfig.json src/server/server.ts"
}

project structure:

<project_root>/
-- tsconfig.json
--src/
 server.config.ts
 --server/
 -- typings/
 -- hapi/
 -- index.d.ts
 server.ts
 tsconfig.json

contents of typings/hapi/index.d.ts:

import {ServerOptionsCache} from 'hapi';

declare module 'hapi' {
 interface ApplicationState {
 cache?: ServerOptionsCache;
 }
}

base tsconfig.json:

{
 "compilerOptions": {
 "lib": [
 "dom",
 "es6",
 "dom.iterable",
 "scripthost",
 "es2017"
 ],
 "jsx": "react",
 "noEmit": true,
 "noErrorTruncation": true,
 "skipLibCheck": true,
 "noUnusedLocals": true,
 "noUnusedParameters": true,
 "allowSyntheticDefaultImports": true,
 "esModuleInterop": true,
 "pretty": true
 }
}

src/server/tsconfig.json:

{
 "extends": "../../tsconfig.json",
 "compilerOptions": {
 "module": "commonjs",
 "experimentalDecorators": true,
 "target": "ES5",
 "moduleResolution": "node",
 "sourceMap": true,
 "typeRoots": [
 "../../node_modules/@types",
 "./typings/hapi"
 ]
 },
 "include": [
 "../server",
 "../server.config.ts"
 ],
 "exclude": [
 "../client"
 ]
}

@blakeembrey did try your approach, still having this issue with 8.0.2 😞

[blakeembrey]

@kgaregin Your typeRoots should be only "./typings". Does that work now?

[3mard]

@kgaregin here is an example of extending express request https://github.com/3mard/ts-node-example

[p-kuen]

Updating tsconfig.json like this works for me now:

{
 "compilerOptions": {
 "sourceMap": true, // allow sourcemap support
 "strictNullChecks": true, // enable strict null checks as a best practice
 "strict": true,
 "target": "esnext", // specify ECMAScript target version
 "module": "commonjs",
 "moduleResolution": "node",
 "noImplicitAny": true,
 "declaration": false,
 "typeRoots": ["./node_modules/@types", "./typings"],
 "emitDecoratorMetadata": true,
 "experimentalDecorators": true,
 "outDir": "./build"
 },
 "include": ["./src/", "./typings"],
 "exclude": ["node_modules", ".logs", "upload"]
}

Folder structure is as described in https://github.com/TypeStrong/ts-node#help-my-types-are-missing.

[kgaregin]

looks like it works again with ts-node@8.0.3 version (like this "typeRoots": ["./node_modules/@types", "./typings"])

[VictorioBerra]

I am having this exact same issue and nothing mentioned here works. I am on 8.3.0

[VictorioBerra]

Also, that link about "help my types are missing" mentioned shows this structure:

<project_root>/
-- tsconfig.json
-- typings/
 -- <module_name>/
 -- index.d.ts

But im not sure what to put for <module_name> when my module name is @ABC/module123. You cannot have slashes in a folder name.

[VictorioBerra]

/// <reference types="./types/untyped_js_lib" /> was the solution that finally worked for me.

[tnganth]

@VictorioBerra possibly:

<project_root>/
-- tsconfig.json
-- typings/
 -- @ABC/
 --modules123/
 -- index.d.ts

The above solution worked for me, having this exact folder structure with my global types in a 'typings' folder

[zerubeus]

When using with ts-node you have to add --files flag

ts-node --files src/server.ts 

[samuraime]

folder structure

<project_root>/
-- tsconfig.json
-- src/
 -- types
 -- global
 -- index.d.ts

tsconfig.json

 "compilerOptions": {
 "typeRoots": [
 "./src/types",
 "./node_modules/@types"
 ]
 },

This works for me. and index.d.ts's name must be index.
