# Change log

# 2.0.0

# Export changes

Changed export paths to not use /dist/, e.g.:

• 'immaculata/dist/jsx-strings.js' => 'immaculata/jsx-strings.js'
• 'immaculata/dist/*.js' => 'immaculata/*.js'

# FileTree changes

• Changed fileTree.watch to not take fn anymore
• Changed fileTree.watch to return EventEmitter with filesUpdated event
• Changed fileTree.watch to take debounce instead of opts: { debounceMs }
• Fixed fileTree.watch when called multiple times (no-op, returns same emitter)
• Added fileTree.onModuleInvalidated to be called inside modules
• Added fileTree.addDependency for module invalidation
• Added moduleInvalidated event to fileTree.watch() events
• Moved fileTree.enableImportsModuleHook to hooks.useTree

# Hook changes

• Put all hooks under hooks namespace from main export
  • Also exported individually from 'immaculata/hooks.js'
• Moved fileTree.enableImportsModuleHook to hooks.useTree
• Removed jsxRuntimeModuleHook as too specific
• Added hooks.mapImport to replace jsxRuntimeModuleHook
• Renamed exportAsStringModuleHook => hooks.exportAsString
• Renamed tryTsTsxJsxModuleHook => hooks.tryAltExts
• Renamed compileJsxTsxModuleHook => hooks.compileJsx

# DevServer changes

• Fixed double-encode of default data on HMR reload

# 1.2.0

The ignore option of .watch(...) was from when it just forwarded options to chokidar. But we usually also want to exclude files with given paths from the tree itself. So the option has been removed in favor of a new exclude option in the constructor.

And since we already keep an in-memory file tree (that's the whole point of FileTree), it turned out to be very easy to give a highly detailed report of what actually changed. So the onChange callback to .watch(...) now receives FileTreeChange[] where:

export type FileTreeChange = { path: string, change: 'add' | 'dif' | 'rem' }

• Added opts?: { exclude: (path: string, stat: fs.Stats) => any } to FileTree constructor
• Added debounceMs option to FileTree.watch
• Added FileTree.addDependency method
• Removed ignore option from FileTree.watch
• Changed onChange callback parameter type of FileTree.watch
• The onChange callback is no longer called when a file is saved but unchanged

# 1.1.0

Removed tree.processFiles as being too trivial and restrictive.

To upgrade, replace:

const result = tree.processFiles(files => {
  // ...
})

with:

const files = Pipeline.from(tree.files)
// ...
return files.results()

(In fact, that's literally all the method originally did.)
