Using non-typed NPM packages in TypeScript
Using untyped NPM packages with TypeScript is not type-safe because types are missing.

To help TypeScript developers use such packages, there is a community-maintained project called Definitely Typed.

Definitely Typed is a project that provides a central repository of TypeScript definitions for NPM packages which do not have types.

Example

npm install --save-dev @types/jquery
Usually, no other steps are needed after installing the declaration package.

TypeScript will automatically pick up the types when you use the package.
