Is it necessary for the version of the @types packages in TypeScript to match their non-types packages?

Are @types and untyped packages versioned the same way?

npm i bluebird @types/bluebird -S
returns

"@types/bluebird": "^3.5.0",
"bluebird": "^3.5.0",

This seems logical.

npm i request @types/request -S yields

"@types/request": "0.0.41",
"request": "^2.81.0",

This situation is concerning. Does this imply that we only have request types available for request version 0.0.41?

Is it necessary for TypeScript @types packages to have matching versions with their non-types counterparts?

Not necessarily. The TypeScript types for JavaScript packages are a best effort and rely on:

  • Official JS documentation (which is often lacking)
  • Community interest in the package

Therefore, version discrepancies are acceptable as long as you acknowledge their nature as a "best effort."
