[dependabot-preview]

Bumps webpack from 4.46.0 to 5.22.0.

Release notes

Sourced from webpack's releases.

v5.22.0

Features

• generate shorter output code for JSON data by using a '...' string instead of "..." (only affects output side when not minimized)
• the dependencies configuration option now works for watch builds too
  • It will build compilation when any of dependencies has changed
  • It will wait for compiling until all of dependencies have finished
• add parallelism config option on the array of configurations to limit the compilers that are running in parallel

Developer Experience

• add hints (Did you mean ...) to resolve errors when
  • resolving fails due to enforceExtension
  • relative request is missing leading ./
• when all modules of an entrypoint fail resolving and another entrypoints depend(s)On it, webpack no longer crashes with a weird error
• add hint to stats how to get details about errors/warnings in child compilations
• improve error message for lazyCompilation when using IE11

Bugfixes

• async entries e.g. for Workers are now implicitly flagged as "having side effects" even if they are affects by "sideEffects": false
  • in future we might add a warning for this
• avoid crash when using this.loadModule (loader) and the loaded module has errors
• refactor libraries to inline exporting code into runtime to allow using with output.iife: false
• fix invalid code when using define for local modules and arrow functions are supported
• fix missing runtime requirement for system.js context
• fix parsing of define function, which missed declarations before
• avoid unnecessary calls to loaders when serializer are already registered
• fix inner graph analysis for exports when export { x } is before pure declaration const x = /*#__PURE__*/ f()
• fix hashing order of runtime chunks when there are async entries involved

Contribution

• CI run tests on node.js 15 too
• CI run tests on github actions too

Experiments

• improvements on experimental output.library: { type: "module" } (experiments.outputModule: true)
  • it can generate export { ... } now, but that can't handle live-bindings yet

v5.21.2

Bugfixes

• json with constructor property now caches correctly
• json generation with object prototype property now works correctly
• tree shaking json array when accessing length property now works correctly
• fix incorrect call context when calling properties on imports from CommonJS modules

v5.21.1
