I have used to set up a new project using React & Typescript. I'm pretty comfortable with JS having used node for an ongoing project, but not familiar with TS where the problem seems to lie.
I have ran the generator with the following environment: typescript, react, webpack w/ NPM, gulp.
When I run gulp serve I get the output below. I'm quite confused why it can't find the files - they are all there on my file system. I've looked at other questions and haven't found anything that resolves my issue

Update: removing target is ok, but removing module is not an option as the compiler depends on it. You can also solve the problem by adding "moduleResolution": "node" to the tsconfig.
TypeScript relies on definition files that define the types, interfaces, etc. for libraries. I'm not familiar with FountainJS, but I'm guessing it's smart enough to create a typings.json file in your workspace. If so, all you need to do is install typings (npm install typings --global) and then use it to install the definitions by doing typings install.
If they didn't include typings.json (though I can't imagine they wouldn't), follow the instructions on their README to search for and install definitions for the dependencies.
I generally add the following lines to package.json so that the typings will be installed automatically any time you run npm install
"scripts": {
"postinstall": "npm run typings",
"typings": "typings install",
}
If you're not familiar with TypeScript, I recommend going through their basic tutorial to get you started: .
you need to ensure the following exists in your tsconfig.json file
{
"compilerOptions": {
...
...
"allowJs": true,
"skipLibCheck": true,
"esModuleInterop": true,
"allowSyntheticDefaultImports": true,
"strict": true,
"forceConsistentCasingInFileNames": true,
"moduleResolution": "node",
"resolveJsonModule": true,
"isolatedModules": true,
...
...
},
"include": ["src", "decs.d.ts"]
}
notice this line
"include": ["src", "decs.d.ts"]
ensure that you create the file decs.d.ts in the folder src
so the content of the file src/decs.d.ts should be
declare module 'jwt-decode';
where jwt-decode is the name of whatever ts module you need to import
And that should resolve the can not find module error
The fix for me was to use tsconfig-paths.
yarn add --dev tsconfig-paths
ts-node -r tsconfig-paths/register script.ts
