Change Log

5.0.0

Major Changes

• 88e0761: Rewritten dependecny tree processing with support for wildcard re-exports.
• cb853e1: All processing stages were merged into one generators-based processor. It allows the implementation of more complex workflows to support features like dynamic imports and re-exports.

Minor Changes

• 9cb4143: Refactoring of the 1st stage of transformation. It opens the road to processing wildcard reexports.
• ae162f4: babelrc should not be used for preeval transformations (fixes #1308)

Patch Changes

• b3ef8c1: fix: add support for params in dynamic imports
• f8b9bff: Improved exports finder so it works with pure TS files and better detects transpiled reexports.
• 6390233: The exports finder didn't support enums that were transpiled to esm by tsc. Fixed.
• aa10045: In some cases, an asynchronous resolver could cause race conditions. Fixed.
• 2a1e24a: Upgrade TypeScript to 5.2
• 16320d7: Prototype methods assignments cannot be deleted safely, so it is replaced with a dummy function.
• Updated dependencies [9cb4143]
• Updated dependencies [88e0761]
• Updated dependencies [9bb782d]
• Updated dependencies [2a1e24a]
• Updated dependencies [cb853e1]
  • @linaria/logger@5.0.0

4.5.3

Patch Changes

• 10bcd24: Fix for "The expression evaluated to 'undefined'" in Webpack (fixes #1300 and #1287)

4.5.2

Patch Changes

• 7955724: Nothing has changed. Just moved some utils and types from babel to utils package.
• b191f54: New option features for fine-tuning the build and evaluation process.
• e59bf80: Shaker mistakenly counts references in types as valuable and keeps referenced variables alive.
• 520ba8d: Debug mode for CLI, Webpack 5 and Vite. When enabled, prints brief perf report to console and information about processed dependency tree to the specified file.
• ae3727f: Fix the issues with processing files that are supposed to be parsed with their respective Babel config.
• dca076e: All references in unary operators should be treated as references, not as bindings. That fixes usages of +exp in interpolations.

4.5.1

Patch Changes

• 85e74df: Fix: type imports without type annotation may lead to an unexpected increase in the evaluated codebase.
• 1bf5c5b: The cache has been improved, which should address the build time issues for Webpack 4/5 and resolve HMR-related problems for Vite. Fixes #1199, #1265 and maybe some more.

4.5.0

Minor Changes

• 16c057d: Breaking Change: Performance Optimization for styled

  When a component is wrapped in styled, Linaria needs to determine if that component is already a styled component. To accomplish this, the wrapped component is included in the list of variables for evaluation, along with the interpolated values used in styles. The issue arises when a wrapped component, even if it is not styled, brings along a substantial dependency tree. This situation is particularly evident when using styled to style components from third-party UI libraries.

  To address this problem, Linaria will now examine the import location of the component and check if there is an annotation in the package.json file of the package containing the components. This annotation indicates whether the package includes other Linaria components. If there is no such annotation, Linaria will refrain from evaluating the component.

  Please note that this Breaking Change solely affects developers of component libraries. In order for users to style components from your library, you must include the linaria.components property in the library's package.json file. This property should have a mask that covers all imported files with components. Here's an example of how to specify it:

  "linaria": {
    "components": "**/*"
  }

Patch Changes

• 8590e13: Fix for incorrect shaker behaviour when it tries to keep a function declaration with a removed body (fixes #1036).
• 8f90fa7: If an expression in a string literal is deleted during preeval stage, it should be replaced with an empty string. Fixes #1039.
• ac0991a: Better detection for jsx-runtime. Reduces the amount of evaluated code and improves speed and stability.

4.1.1

Patch Changes

• 50bc0c7: Fix for "Property key of ClassMethod expected to be" (fixes #1030)

4.0.0

Major Changes

• bc0cbee: A completely new async mode with native support for Vite, Rollup, esbuild and Webpack resolvers.

  BREAKING CHANGES: Despite the fact, that it should be fully compatible with 3.0 and 2.0 branches, the new version of styles evaluator can have some serious bugs which can make your project unbuildable (however, since there is no runtime, if the build is finished successfully, everything will continue work as it was on 2.0 and 3.0). If you face some problems please let us know and we will fix it as soon as possible.
