This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to master, this PR will be updated.

Major Changes

• #1647 03b8f9d Thanks @rschristian! - Drops support for Preact v8

preact-cli@4.0.0

Major Changes

• #1647 03b8f9d Thanks @rschristian! - Drops support for Preact v8

• #1647 03b8f9d Thanks @rschristian! - Alters CSS Module detection to instead rely upon file names, rather than directory names.

  Treating all CSS files found within routes/ and components/ as CSS Modules was not obvious, nor did it offer an easy way to opt out (or in) without editing the Webpack config itself.

  This change makes is so that users can opt into CSS Modules from anywhere in their app by instead naming their CSS files according to the pattern *.module.css.

  Anyone using CSS Modules within routes/ or components/ will need to alter their CSS files to be x.module.css. If you've disabled CSS Modules in your preact.config.js, you can remove that bit of configuration and use file names to instead determine behavior.

• #1647 03b8f9d Thanks @rschristian! - Reduces the env parameter of preact.config.js to only contain 3 values: isProd, isWatch, and isServer.

  Previously, env contained many semi-duplicated values (production and isProd, etc) as well as values that were unlikely to be of much use to many users (what flags were set, for instance). Because of this, the signal-to-noise ratio was rather low which we didn't like. As such, we reduced env down to the most basic environment info: what type of build is preact-cli doing and for which environement?

  If you customize your Webpack config using a preact.config.js, please be aware that you may need to update which values you consume from env.

• #1647 03b8f9d Thanks @rschristian! - To increase transparency and user control over the template.html, <% preact.headEnd %> and <% preact.bodyEnd %> will no longer be supported; instead, users should directly adopt the EJS and keep it in their templates.

  In the past, these were abstracted away as they were a bit unwieldy; EJS might be unfamiliar with users and the way data was retrieved from html-webpack-plugin was somewhat less than elegant. However, this has much improved over the years and the abstraction only makes simple edits less than obvious, so it is no longer fulfilling it's purpose.

  New projects will have a template.ejs created in place of the old template.html, containing the full EJS template. For existing projects, you can copy the default template.ejs into your project or adapt it as you wish.

• #1647 03b8f9d Thanks @rschristian! - HMR / the --refresh flag is now enabled by default in dev mode.

• #1647 03b8f9d Thanks @rschristian! - Changes the JSX transform from 'classic' to the newer 'automatic'

  Users will no longer need to add import { h } from 'preact' in their components; it will be done automatically for them.

• #1647 03b8f9d Thanks @rschristian! - Removes --preload flag and functionality from build command.

• #1647 03b8f9d Thanks @rschristian! - Removes --json & --brotli flags from preact build. Also removes --rhl alias for --refresh from preact watch.

• #1647 03b8f9d Thanks @rschristian! - Updates to use html-webpack-plugin v4

• #1647 03b8f9d Thanks @rschristian! - - Upgrades to Webpack v5

  • Any custom configuration you do in your preact.config.js may need to be altered to account for this. Plugins may need replacements or different option formats.

  • --esm flag has been removed

    • Dual output is now enabled by default in production builds.

  • .babelrc no longer overwrites matching keys

    • Instead, the config will be merged in to the default. The default still takes precedence when there are conflicts, so you will still need to use your preact.config.js if you want to edit or remove default plugins or presets.

• #1647 03b8f9d Thanks @rschristian! - Minimum supported Node version for preact-cli is now v14.14.0. Please upgrade if you are on an older version.

  build and watch commands will no longer take an optional src directory argument; if you want to change the source directory from the default (./src), please instead use the --src flag (i.e., --src differentSrc).

  Upon rebuild, the output directory will no longer be outright deleted; instead, it will be emptied. This has the benefit of better supporting containerized environments where specific directories are mounted. Emptying the directory, rather than deleting and recreating it, ensures a stable reference for those tools.

• #1647 03b8f9d Thanks @rschristian! - Extracts project creation functionality from preact-cli into create-preact-cli

  Setting up new preact-cli projects with npx is slow, as all dependencies of preact-cli would need to be installed, even though only a handful are used for project initialization. On the other hand, suggesting global installs is less than attractive due to NPM's poor default install location (requires sudo) and this can get out of sync over time.

  By extracting project initialization into its own package, we can provide much, much faster project setup times.

  To setup a new project, users will use npm init preact-cli ... or yarn create preact-cli ....

  Additionally, the --yarn flag has been removed in favour of using the yarn initializer (yarn create).

Patch Changes

• #1647 03b8f9d Thanks @rschristian! - Disables hash in CSS file names for the SSR build

• #1814 1777c90 Thanks @rschristian! - Fix for incorrect minification in some specific circumstances. Files should now minify slightly better too.

• Updated dependencies [03b8f9d]:
