Steps to Reproduce

All I had to do was update my fastify version from 3.x to 4.x and run ‘tsc’

Expected Behavior

No errors and tsc succeeds

[Aras Abbasi]

We are not supporting unreasonable old typescript versions.

[Chris Tully]

I do not expect you to support the 3.x version!

but I would expect 4.x to be compatible with typescript and tsc given that the current docs have a whole section on using fastify with typescript.

[Aras Abbasi]

Your first wrong assumption is that typescript would be using semver. It is not. Every typescript minor version is breaking the previous minor version.

https://www.learningtypescript.com/articles/why-typescript-doesnt-follow-strict-semantic-versioning#typescript-versioning-today

You could basically say, that version 4.0 is actually semver version 40. current version 5.3 is actually semver version 53.

So if you are using typescript 4.0 you are 13 semver major versions - or more than 3 years - behind latest typescript version.

Upgrade your typescript version.

[Chris Tully]

Ok, I will attempt to update Typescript. But given the nearly global acceptance of Semver, it was a reasonable assumption for me as a newbie to both fastify and typescript.

Agreed. You should make that known to the TS project. (Foreshadowing: they won't care.)

[Chris Tully]

Upgrading typescript did the trick. Thank you.
