Big Refactors

  • The underlying structure of the runtime changed from class components to functional components and signals, this allows a two level structure (components have internal entities otherwise is everything is one level)
  • The error messages have been reworked internally, texts were reviewed, and the UI is a bit simpler, all in all it's easier to work with internally.
  • The compiler was fully refactored to emit ES5 modules and to support code-splitting.
  • All commands now use the same bundler (development server, builder, test runner) instead of their own implementation.
  • How variables are resolved has been rewritten from scratch.

Performance

The development server was type checking twice on each change, and it was checking everything. Now it only checks what the application is actually using, and it checks only once.

Language

  • Added async keyword for components (to be loaded later from a different file).
  • Added return keyword for early returns in blocks with destructuring.
  • Added defer keyword for loading code from different files.
  • Added builtins feature for interfacing with the runtime.
  • Added syntax sugar for creating maps: { key => value }.
  • Added syntax sugar for setting state: -> name.
  • Added highlight parameter for here documents.
  • Added @highlight-file directive.
  • Allow routes to be await-ed to wait with the hash navigation.
  • Allow grouping inline comments (for documentation purposes).
  • Allow full destructuring in if lets.
  • Allow functions in test suites.
  • Expressions can now be used as children of Html as is (no Html expression is needed).
  • Arguments with default values are now typed, checked against the defined type.
  • Html expressions <{...}> are deprecated in favor of Html fragments <></>.
  • Field access .name now requires the type as a parameter .name(User).
  • <, >, <=, >= operators are now only work with numbers.
  • Removed the feature of memoizing static virtual DOM nodes.
  • record and enum keywords are replaced by type.
  • &&, || operators now only work with booleans.

Maintenance

  • Support ARM mac in build workflow.
  • Dry CI workflows (Crystal latest / nightly).

Standard Library

  • Code is updated to reflect the changes in the language (use builtins, changed keywords, etc…).
  • Dom.setValue now returns the element when setting the value to empty string.
  • Some Array functions have been refactored to not use inlined JavaScript.
  • Removed Html.fromEvent (was used internally).
  • Convert FileSize.format to Mint only.
  • Added Test.Context.assert function.

Runtime

The runtime has been refactored and moved into the repository (the other will be archived).

Formatter

  • Update formatting of listed entities (honor whitespace).
  • Added missing @font-face formatter.

Language Server

  • Improve here document and string literal highlighting (semantic tokenizer).

CLI

  • Most commands have been reviewed and changes were made to them.
  • The --env flag is now local to commands that can use them.
  • Removed compile command since it's no longer possible to emit a single JS file.
  • Removed docs command temporary (it will be added back in a future release).

build

  • The command is now less verbose by default.
  • The generated assets are now stored in the __mint__ directory instead of assets.
  • --skip-service-worker flag was removed, since no service worker is generated now.
  • --inline flag was removed, it's no longer possible to emit a single HTML file.
  • --skip-manifest flag was removed, manifest is now not generated by default.
  • --minify flag was removed, code is optimized by default.
  • Added --timings flag to show more information about the build process.
  • Added --generate-manifest flag to generate a web application manifest.
  • Added --no-optimize flag to disabled optimization.
  • Added --verbose flag to show the generated files.
  • Added --env flag.
