A BRIEF HISTORY OF SPECIFIERS AND PROTOCOLS

Summary from the TLDR Dev newsletter

Node.js introduced the node: protocol in 2021. Deno intro dude https imports in 2018, and then the npm: protocol in 2022. Deno then introduced package.json support in 2023 and the jsr: protocol in 2024. Also in 2024, Deno started moving away from HTTP imports. The current landscape is a messy state of affairs.
