From 0706ace6080af8aabc6a9971edaa7086f070d9bb Mon Sep 17 00:00:00 2001 From: Ruben Fiszel Date: Thu, 29 Jan 2026 01:44:40 +0000 Subject: [PATCH] feat: add QuickJS as alternative JS engine for flow expression evaluation (#7664) * feat: add QuickJS as alternative JS engine for flow expression evaluation Add rquickjs as an optional alternative to deno_core for evaluating JavaScript expressions in flow transformations. QuickJS offers ~8-16x faster startup times for simple expressions, making it ideal for evaluating many small expressions in flows. Key changes: - Add new `quickjs` feature flag for windmill-worker - Implement js_eval_quickjs.rs with true async Rust callbacks for variable(), resource(), and results.xxx access (no pre-fetching) - Share expression transformation logic (replace_with_await, replace_with_await_result) between both implementations - Add USE_QUICKJS_FOR_FLOW_EVAL env var to switch engines at runtime - When only quickjs feature is enabled (no deno_core), QuickJS is automatically used - Add comprehensive parity tests comparing QuickJS and deno_core output Co-Authored-By: Claude Opus 4.5 * all * quickjs * quickjs * all * all * all --------- Co-authored-by: Claude Opus 4.5 --- backend/Cargo.lock | 70 +- backend/Cargo.toml | 5 +- backend/QUICKJS_MIGRATION_ANALYSIS.md | 370 ++ backend/tests/flow_engine_parity.rs | 1814 ++++++++ backend/windmill-worker/Cargo.toml | 5 +- backend/windmill-worker/src/js_eval.rs | 45 +- .../src/js_eval_parity_tests.rs | 4045 +++++++++++++++++ .../windmill-worker/src/js_eval_quickjs.rs | 788 ++++ backend/windmill-worker/src/lib.rs | 4 + 9 files changed, 7136 insertions(+), 10 deletions(-) create mode 100644 backend/QUICKJS_MIGRATION_ANALYSIS.md create mode 100644 backend/tests/flow_engine_parity.rs create mode 100644 backend/windmill-worker/src/js_eval_parity_tests.rs create mode 100644 backend/windmill-worker/src/js_eval_quickjs.rs diff --git a/backend/Cargo.lock b/backend/Cargo.lock index e826db4540..825a322a3e 100644 --- a/backend/Cargo.lock +++ b/backend/Cargo.lock @@ -1842,7 +1842,7 @@ source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "0686c856aa6aac0c4498f936d7d6a02df690f614c03e4d906d1018062b5c5e2c" dependencies = [ "once_cell", -

QuickJS-based JavaScript expression evaluation for flow transformations. +//! +//! This module provides an alternative to deno_core for evaluating arbitrary JavaScript +//! expressions in flow transformations. QuickJS offers significantly faster startup times +//! (~200μs vs ~3ms for V8), making it ideal for evaluating many small expressions. +//! +//! ## Performance Characteristics (release mode benchmarks) +//! - **Simple expressions**: ~238μs (QuickJS) vs ~3.05ms (deno_core) = **~13x faster** +//! - **Complex expressions**: ~192μs (QuickJS) vs ~3.09ms (deno_core) = **~16x faster** +//! - **Memory**: ~2.5% of V8's footprint +//! +//! For flow expression evaluation where startup time dominates, QuickJS is significantly +//! faster overall despite being slower for long-running CPU-intensive code. +//! +//! ## Async Operations +//! This implementation uses true async Rust callbacks (similar to deno_core's ops) for +//! `variable()`, `resource()`, and `results.xxx` access. The async functions use +//! rquickjs's `Async>` wrapper which returns JavaScript Promises that are +//! resolved when the Rust async operations complete.
