I. News

1.1 Recent Version Releases:

The current version of this repository is v23.10.0

1.2 Version Information:

Released on March 13, 2025, this version introduces the --experimental-config-file feature, allowing developers to use JSON configuration files like node.config.json to simplify flag management for test runners and other experimental features, enhancing developer experience. Additionally, it includes updates to root certificates, new TLS and V8 methods, improved error handling, and various tooling and documentation enhancements.

II. Issues

2.1 Top 5 Active Issues:

We consider active issues to be issues that that have been commented on most frequently within the last week. Bot comments are omitted.

1. [LOADERS] Proposal: new vm module primitives & loader API for ESM customization: This issue proposes a new design for the Node.js vm module to replace the existing vm.SourceTextModule with new primitives and a high-level loader API aimed at customizing ESM loading. The goal is to address current API limitations such as memory leaks, error handling difficulties, and excessive boilerplate by introducing a SourceTextModuleLoader abstraction that can be subclassed for full or partial customization, enabling better control over module resolution, linking, and evaluation within VM contexts.

   • The comment discussion extensively explores practical use cases and concerns from testing frameworks like Jest and Vitest, focusing on cache invalidation, mocking, synchronous vs asynchronous evaluation, built-in module handling, and lifecycle management of loaders; the conversation also covers API design choices such as subclassing versus constructor options, error model distinctions, integration with existing hooks, and future support for WebAssembly and CJS interoperability, with broad agreement on the proposal’s direction and suggestions for incremental improvements and clarifications.
   • Number of comments this week: 3

2. [WRONG REPO] Support/Use node_modules out-of-tree.: This issue discusses the challenge of configuring the node_modules directory to be located outside the source tree in development environments using pnpm and devcontainers, where bind mounting causes problematic symlinks and hardlinks. The user is seeking alternatives or support for out-of-tree node_modules paths to avoid these issues in containerized setups.

   • The comments clarify that this question is out-of-scope for the Node.js repository as it pertains to npm/pnpm usage rather than Node.js core functionality, directing the user to community discussions for npm and pnpm; it is also noted that NODE_PATH is still supported and the issue was re-opened for further input, but better advice is expected from the pnpm community.
   • Number of comments this week: 3

3. [V8 ENGINE] Large argv leaves V8 no stack on macOS: RangeError at bootstrap, before the first JS frame: This issue describes a problem on macOS where passing a very large command-line argument to Node.js causes V8 to run out of stack space during its bootstrap phase, resulting in a RangeError before any user JavaScript code executes. The root cause is that the kernel places the argv and environment block at the top of the main thread's stack, leaving no room for V8's stack limit calculation, which leads to a stack overflow when the argument size exceeds a certain threshold but is still under the system's ARG_MAX.

   • The comments confirm reproduction of the issue locally and plan to investigate the stack budget and propose a fix involving resizing the main-thread stack during bootstrap; however, it is also noted that a recent V8 commit may have addressed this, and since extremely large command-line arguments are uncommon, the issue might be closed as informational unless a real-world use case arises.
   • Number of comments this week: 2

4. test_runner: source-mapped coverage resolves ranges starting at column 0 to the previous line, so executed functions report as uncovered under off-thread module hooks: This issue describes a problem in the Node.js test_runner subsystem where source-mapped coverage incorrectly resolves code ranges starting at column 0 to the previous line, causing functions executed under off-thread module hooks to be reported as uncovered. The problem arises because coverage records from the main thread and hooks thread do not merge correctly due to differences in source mapping and offset calculations, leading to inaccurate coverage reports when using off-thread hooks like module.register() or --experimental-loader.

   • The comments include a request from a user to be assigned the issue, followed by a response noting that the issue is unlikely to be fixed due to the deprecation of module.register() and the planned removal of async hooks, suggesting the issue may be closed unless a Node team member decides otherwise.
   • Number of comments this week: 2

5. TextEncoder.encodeInto() underfills the destination for some non-ASCII text: This issue reports two bugs in the TextEncoder.encodeInto() method that cause encoding to stall incorrectly when encoding certain non-ASCII characters, specifically due to an incorrect byte length calculation and signed-byte handling introduced in a recent Node.js performance update. The reporter provides detailed examples demonstrating these problems and proposes specific code fixes to address the incorrect cutoff in character length calculation and the signed-byte handling in the encoding function.

   • The comments acknowledge the detailed report and proposed fixes, with one contributor opening a pull request that includes tests and improvements based on the issue, and the original reporter confirming the validity of the surrogate-pair underfill problem and expressing approval of the proposed solution.
   • Number of comments this week: 2

2.2 Top 5 Stale Issues:
