`ignore` (node-ignore) is a pure JavaScript manager, filter, and parser for .gitignore rules, implemented to follow the .gitignore spec. It’s useful for filtering file paths in Node.js tooling, and it is used by projects like eslint and prettier (and others) to apply ignore-pattern logic.

Recent updates
7.0.5
5/31/2025Release 7.0.5 is a small patch bump with minimal user-facing documentation changes. The main code change refactors the Windows-specific initialization logic and adjusts tests to call that setup explicitly.
7.0.4
4/25/2025Release 7.0.4 is a patch update that fixes handling of ignore patterns involving filenames that are composed only of three or more dots (for example, `...`). The main behavior change is in path validation logic, and the release notes specifically mention avoiding a RangeError seen in prior versions.
7.0.3
1/14/2025Release 7.0.3 was published, but no release notes or changelog content was provided by the publisher. Without documented changes, the impact on API compatibility, behavior, and migration requirements cannot be determined from the release notes alone.
7.0.0
12/23/2024Version 7.0.0 adds a new `.checkIgnore()` API intended to emulate `git check-ignore -v`, and extends `.add()` to accept `{pattern, mark?}` so rule marks can be surfaced. The implementation also refactors how ignore rules compile regexes, introducing separate matching behavior for “normal ignore” versus “check-ignore” mode.
BreakingFeatures6.0.1
9/28/2024The release notes for version 6.0.1 claim that upgrading from 5.x to 6.x changes nothing and causes no harm, and that 6.x was a mistake. However, the code diff shows multiple real behavior and packaging changes, including updates to the ignore-rule parsing logic, addition of an ESM entrypoint (index.mjs), and test/CI/TypeScript adjustments.
BreakingFeatures5.3.0
11/16/2023Release 5.3.0 primarily updates the TypeScript type definitions by exporting the `Options` interface. The code diff also shows repository-level and dev-tooling changes (CI Node version updates, devDependency bumps, and test adjustments), none of which are mentioned in the release notes.
Features5.2.4
12/19/2022Release 5.2.4 is a patch update focused on correcting .gitignore pattern handling for wildcards and preventing unexpected failures when ignore patterns end with a trailing backslash. The code changes align closely with the release notes, with additional internal/test/CI adjustments present in the diff.
5.2.0
12/19/2021Version 5.2.0 adds TypeScript-friendly support for readonly arrays, and introduces an option to avoid throwing when testing ignore rules with non path.relative() compliant paths (relative path compatibility). The code changes largely align with the release notes, but there are additional option and TypeScript typing adjustments not mentioned in the provided release notes.
Features5.1.9
11/3/2021Release 5.1.9 is a patch release that fixes incorrect handling of the ignorecase option when the module hits its internal regex cache. The code change refactors how cached regexes are produced and adds a targeted test to prevent regressions for mixed ignorecase usage on the same pattern.
5.1.5
5/22/2020Release 5.1.5 is presented as a patch that fixes escaping for square brackets (issue #59). The code diff shows a more substantial rewrite of the .gitignore-to-regex escaping pipeline, especially around bracket/range handling and unescaping behavior, plus multiple dev tooling and CI configuration updates.
5.1.3
8/14/2019Release 5.1.3 is a patch release that claims to apply updated gitignore rule handling from gitignore 2.22.1 and includes a fix for issue #56. The code changes do more than just adjust one matching rule, including a refactor of how ignore rule patterns are converted into regexes.
Breaking5.1.1
4/17/2019Release 5.1.1 is a patch that fixes Windows path validation so absolute Windows paths are handled correctly. It introduces internal refactoring around path normalization and validation, and ensures Windows absolute paths are rejected with the expected error behavior for ignore/test-related APIs.
