fix: add type declaration paths to exports field

[andipaetzold]

With TypeScript 4.7, a new module was introduced: Node16. https://devblogs.microsoft.com/typescript/announcing-typescript-4-7/#esm-nodejs

When using strict mode with module Node16, you receive the following error message because the type declaration cannot be found:

Could not find a declaration file for module 'csv-stringify'. '.../node_modules/csv-stringify/dist/cjs/index.cjs' implicitly has an 'any' type.
  Try `npm i --save-dev @types/csv-stringify` if it exists or add a new declaration (.d.ts) file containing `declare module 'csv-stringify';`

Reproduction

Create a new project with the following dependencies

• typescript: 4.7.2
• csv-stringify: 6.1.0

Create the following files:

// tsconfig.json
{
    "compilerOptions": {
        "module": "Node16",
        "strict": true
    }
}

// index.ts
import { stringify } from 'csv-stringify';

When building the project, you receive the error message above.

Solution

This issue can be solved by adding the types to the exports field in package.json

In packages/csv-generate/package.json, the stream field was removed. Could you place it back, thank you.

Done. Copy paste 🤦

The require path of csv-generate/stream (dist/cjs/stream.cjs) does not exist in the final bundle. I assume there is a build step missing.
