Under the hood,
ts-morph to read
TypeScript source files of all entities to be able to detect all types. Thanks to this,
defining the type is enough for runtime validation.
This process can be a bit slow, mainly because
ts-morph will scan all your source files
based on your
tsconfig.json. You can speed up this process by whitelisting only the folders
where your entities are via
After the discovery process ends, all metadata will be cached. By default,
will be used to store the cache inside
./temp folder to JSON files.
Entity metadata are cached together with modified time of the source file, and every time the cache is requested, it first checks if the cache is not invalid. This way you can forgot about the caching mechanism most of the time.
One case where you can end up needing to wipe the cache manually is when you work withing a git branch where contents of entities folder differs.
You can disable caching via:
You can set the temp folder via:
You can also implement your own cache adapter, for example to store the cache in redis.
To do so, just implement simple
And provide the implementation in
