Lots of built-in collections and methods produce subtypes of`IteratorObject` s (like`ArrayIterator`,`SetIterator`,`MapIterator`, and more), and both the core JavaScript and DOM types in`lib.d.ts`, along with`@types/node`, have been updated to use this new type. ... Note that while this option may overlap a bit with`typescript.preferences.autoImportFileExcludePatterns`, there are differences. The existing`autoImportFileExcludePatterns` takes a list of glob patterns that exclude file paths. This might be simpler for a lot of scenarios where you want to avoid auto-importing from specific files and directories, but that’s not always enough. For example, if you’re using the package`@types/node`, the same file declares both`fs` and`node:fs`, so we can’t use`autoImportExcludePatterns` to filter out one or the other. ... The new`autoImportSpecifierExcludeRegexes` is specific to module specifiers (the specific string we write in our`import` statements), so we could write a pattern to exclude`fs` or`node:fs` without excluding the other. What’s more, we could write patterns to force auto-imports to prefer different specifier styles (e.g. preferring`./foo/bar.js` over`#foo/bar.js`). <title>In TypeScript 5.6+, `Buffer` is not assignable to `ArrayBufferView` or `Uint8Array | DataView`</title> https://stackoverflow.com/questions/78790943/in-typescript-5-6-buffer-is-not-assignable-to-arraybufferview-or-uint8arr # In TypeScript 5.6+, `Buffer` is not assignable to `ArrayBufferView` or `Uint8Array | DataView` - Tags: javascript, node.js, typescript, npm, upgrade - Score: 42 - Views: 12,797 - Answers: 1 - Asked by: Daniel Rosenwasser (24,261 rep) - Asked on: Jul 24, 2024 - Last active: Jul 23, 2025 - License: CC BY-SA 4.0 --- ## Question Trying to upgrade to TypeScript 5.6 Beta, I get the following error messages in `node_modules`.

You can adapt any existing `Iterable`s into this new type with `Iterable.from`: ``` Iterator.from(...).filter(someFunction); ``` Now whenever a built-in method, or a generator, produces one of these `IterableIterator`s, it is backed by the methods on `Itera…[truncated]

Raise the TypeScript minimum to ^5.6.0. The lockfile currently resolves TypeScript to 5.9.3, but package.json still permits TypeScript 5.3.x through 5.5.x. Those versions are outside the supported range for @types/node 26 and can fail when the lockfile is regenerated with an older compatible resolution.
