We’ve heard you: One of the biggest reasons ESLint users haven’t upgraded to ESLint v9.x is migrating a configuration file seems difficult and complicated. Some plugins support flat config and the ESLint v9.x rule APIs and some don’t. Sometimes you need to use FlatCompat and sometimes you need to use the compatibility utilities. While we cover as much as we can in the migration guide, it can take

The release of ESLint v9.0.0 brought with it the rollout of the new configuration system, but also a series of changes to the rules API. These changes are necessary in order to prepare ESLint for implementing language plugins, which will give ESLint the ability to natively lint languages other than JavaScript. As a result, plugin authors needed to update their rules to work with v9.0.0, and unfort

As of ESLint v9,0.0, the new configuration system has reached general availability, bringing with it many benefits. Configuration files are now easier to manage and more transparent to compose. However, it can still be non-trivial to understand which rules are enabled and disabled for specific files, especially when your configuration is complex or composed from multiple sources. That’s why we are

In ESLint v8.53.0, scheduled to be released on Friday, November 3, 2023, we will formally deprecate our formatting rules. Formatting rules are those rules that simply enforce code conventions around spacing, semicolons, string formats, etc. For a variety of reasons, which are discussed in this post, this is the right decision for ESLint going forward. However, to understand how we got here, it’s h

It may seem hard to believe, but the RFC for ESLint’s new configuration system, nicknamed flat config, was first written in 2019. It took until 2022 (v8.21.0) for us to release an experimental, opt-in version of flat config. Since then, we’ve been making changes and improvements based on feedback from the community. The plan was always to allow the current configuration system, nicknamed eslintrc,

When ESLint v9.0.0 is released, it will ship with several breaking changes for rule authors. These changes are necessary as part of the work to implement language plugins, which gives ESLint first-class support for linting languages other than JavaScript. We’ve had to make these changes because ESLint has, from the start, assumed that it would only ever be used to lint JavaScript. As such, there w

In my previous post, I talked about how the eslintrc config system had grown to be more complex than necessary through a series of small, incremental changes. The flat config system, on the other hand, was designed from the start to be simpler in a number of ways. We took all of the learnings from the previous six years of ESLint development to come up with a holistic approach to configuration tha

When ESLint was first released in 2013, the config system was fairly simple. You could define the rules you wanted to enable or disable in a .eslintrc file. When a file was linted, ESLint would first look in the same directory as that file for a .eslintrc file and then continue up the directory hierarchy until reaching the root, merging configurations from all the .eslintrc files found along the w

JavaScript suspends the control flow statements of try and catch blocks until the execution of finally block finishes. So, when return, throw, break, or continue is used in finally, control flow statements inside try and catch are overwritten, which is considered as unexpected behavior.
