General Theme:

Technology:

Fastify: modern, blazingly fast webserver
- mercurius.dev: graphql adapter for fastify
NodeJS undici: a better web client, rewritten from scratch
js-url: a faster version for URL parsing. URL parsing is used in almost every request
autocannon: a handy tool for loadtesting
ClinicJS: a tool to diagnose NodeJS performance issues
Lyrasearch: A blazingly fast full-text search, written by a guy who tried to understand Elasticsearch
Lavamoat: scope npm package access at runtime
The NPM best practices guide
Node API to cross from node to other languages
Node18 Native Test Runner
Socket Runtime: a p2p node runtime
Graphql-yoga: A better graphql server?
Cytoscape-js: a visualization tool used in the industry, talked about it with one engineer. Otherwise he mentioned d3.
NodeSource: Node freaks that build their own runtime. Very cool talk on opentelemetry!
CommonJS vs ES Modules oppinions
web3.storage: blockchain based storage on s3
storj.io: blockchain based decentralized video streaming

General Notes:

Web Assembly is the cool kid
“Promises always fix callback issues”
“Javascript gets slower every time you modify an object”
- Object freezing is shallow
- Cool proposal in progress: Touples#[] and Records #{}
AbortSignal and setTimeout make things slower
- One AbortSignal bug will be removed soon, which will improve the performance of every single node request
- Blog: Using AbortSignal in NodeJS
