Features
Dependency Management
Service
API (recommended to use this over useContainer hooks)- Dependencies type must be globally augmented in order for Services api to function properly
- new methods on ModuleManager
- getPublishableCommands()
- Init Hooks
- implement starting behavior for dependencies
- To enforce and type check this, use the
Initializable
type when making your Dependencies type!
- Emitter interface
- More generic interface to define any event emitter
- You can now swap out the SernEmitter with whatever emitter now.
1class DatabaseService implements Init {2 //some hypothetical database3 _pgsql : database()4
5 async init() {6 await _pgsql.load()7 }8
9}10
11await makeDependencies({12 build: root => root.add({13 db: new DatabaseService() //will be init'ed automatically14 })15})
- new SernEmitter event
modulesLoaded
, which allows users to customize behavior after all modules are loaded!
1export default eventModule({2 name: "modulesLoaded",3 type: EventType.Sern,4 execute: () => {5 console.log("All modules loaded");6 },7});
Quality of Life
-
faster module loading
- I utilize async generators for reading files now. A lot faster than the first iteration.
-
better error handling
-
Less boilerplate
- Services api cleans up v2 boilerplate
-
class modules devex got upgraded and work better than before
-
automatically ignore any files not ending in (mts, cts, mjs, cjs, ts, js)
- ignore commands and events with
!
prefix on filename or directory (ie:!filename.ts
or!directory
will be ignored by sern)
- ignore commands and events with
-

Init Hooks
- implement starting behavior for dependencies
Experimental
- Experimental things may be subject to removal, need feedback and are not guaranteed stable
- dev / prod mode
- sern will behave differently depending on mode set
- init sern from
file
option- reads from local sern.config.json
1Sern.init("file");
Breaking changes
- Sern.makeDependencies -> makeDependencies
- it is asynchronous and top level function now. Make sure to await it before initing for proper synchronization.
- module store and manager internally changed, so those using them may recieve breaking changes
- BaseOptions type removed
Sern.makeDependencies({ build: () => {} })await makeDependencies({ build: () => {} })
Deprecations
- Removed all previous marked deprecations in v3
- ModuleStore will be removed as a dependency in v4. The only way to access modules should be through ModuleManager
- Default Dependencies will be made internal in the v4. Users should only have access to its interface / contract
