核心要点

• Handling data in streams is fundamental to how we build applications. To make streaming work everywhere, the WHATWG Streams Standard (informally known as "Web streams") was designed to establish a common API to work across browsers and servers. It shipped in browsers, was adopted by Cloudflare Workers, Node.js, Deno, and Bun, and became the foundation for APIs like fetch(). It's a significant undertaking, and the people who designed it were solving hard problems with the constraints and tools they had at the time.
• But after years of building on Web streams – implementing them in both Node.js and Cloudflare Workers, debugging production issues for customers and runtimes, and helping developers work through far too many common pitfalls – I've come to believe that the standard API has fundamental usability and performance issues that cannot be fixed easily with incremental improvements alone. The problems aren't bugs; they're consequences of design decisions that may have made sense a decade ago, but don't align with how JavaScript developers write code today.
• This post explores some of the fundamental issues I see with Web streams and presents an alternative approach built around JavaScript language primitives that demonstrate something better is possible.
• In benchmarks, this alternative can run anywhere between 2x to _120x_ faster than Web streams in every runtime I've tested it on (including Cloudflare Workers, Node.js, Deno, Bun, and every major browser). The improvements are not due to clever optimizations, but fundamentally different design choices that more effectively leverage modern JavaScript language features. I'm not here to disparage the work that came before; I'm here to start a conversation about what can potentially come next.
• Where we're coming from

可执行步骤

1. The Streams Standard was developed between 2014 and 2016 with an ambitious goal to provide "APIs for creating, composing, and consuming streams of data that map efficiently to low-level I/O primitives." Before Web streams, the web platform had no standard way to work with streaming data.
2. Node.js already had its own streaming API at the time that was ported to also work in browsers, but WHATWG chose not to use it as a starting point given that it is chartered to only consider the needs of Web browsers. Server-side runtimes only adopted Web streams later, after Cloudflare Workers and Deno each emerged with first-class Web streams support and cross-runtime compatibility became a priority.
3. The design of Web streams predates async iteration in JavaScript. The `for await...of` syntax didn't land until ES2018, two years after the Streams Standard was initially finalized. This timing meant the API couldn't initially leverage what would eventually become the idiomatic way to consume asynchronous sequences in JavaScript. Instead, the spec introduced its own reader/writer acquisition model, and that decision rippled through every aspect of the API.
