This entry point will be used for hot reloading, in order to initially retrieve digests of all assets, as build_runner might not know list of all of them, unlike client.

can we make this longer? Maybe $assetDigets? I'm worried we'll want to use the name $assets for something else.

do we need to store null? Should we instead resultMap.remove(path)?

* Add assets digests handler (#1709) This entry point will be used for hot reloading, in order to initially retrieve digests of all assets, as build_runner might not know list of all of them, unlike client. * Emit useful information about build results (#1710) Instead of just 'update' emit json with updated build results and its digests * Move live reload client code to new hot_reload_client.dart file (#1732) It is expected that client code will become complicated, so in separate dart file it would be easier to test and maintain. * Implement basic hot reload (#1741) Reload any changed modules without any specific order, then reload main module and call main func to hopefully apply changes. Still need to get module dependency graph to reload in topological order and find correct ancessor chain where reloaded modules can be saved in closures. * Basic graph handling for hot reload (#1759) We still lack handling situations when graph is dynamically updated between reloads. * Add rough graph changes handling by full page reload (#1763) * Simplify module interface (#1764) * Change HMR API to work with several libraries bundled in one module (#1765) Fixes #1762 * Close Hot Reload listeners on exit (#1775) Closes #1774 * Refactor and improve HMR code (#1770) - Get rid of `roughLibraryKeyDecode` - use library path exposed from dart runtime now. - Get load modules from cache directly and throw if it isn't loaded instead of using require.js and hoping that module already loaded and no network request would be done. - Don't mess with `.ddc` extension in `build_runner` code - encapsulate all of it on build_web_compilers side. Fixes #1760 Fixes #1762 * Finalize hot-reloading feature (#1773) - Rename live-reload to hot-reload - Add debug logging about reloading - Add documentation - Version bump and changelog Fixes #1766 * Restore --live-reload option (#1778)
