Mat Ryer's: How I Write HTTP Web Services after Eight Years

Compilable code for Mat Ryer's GopherCon 2019 talk, How I Write HTTP Web Services after Eight Years.

I took these notes while watching the talk. I obviously did not create this code, and Mat Ryer has not, as far as I know, licensed it. For this reason, I will be more than happy to take this repo private.

The fact that this code compiles is not that important since it does nothing interesting. But the ANCILLARY STUB sections do show what types might satisfy some of Mat's slide code, and in addition it makes the occasionally inconsistent slide code consistent.

Note

While the code compiles, the tests panic. The stubs compile but in many cases are not valid due to nil pointer dereferencing. This is intentional, since it makes the stubs as minimal as possible. My goal was to make them as close to, e.g., function signatures, as the compiler would let me.
