@raymondfeng I'd like to discuss this before we go and implement the injection. The canonical express way of accessing the app
object is to use req.app
from within the handler function. We are already doing this in loopback.rest().
What is so special about your middleware that it needs the app object outside of the handler function?
from loopback-boot.
Looking at oauth2-loopback.js, the component needs the app
object for two tasks:
- Register middleware prerequisites
var session = (options.session !== false);
app.middleware('auth:before', passport.initialize());
if (session) {
app.middleware('auth', passport.session());
}
- Setup models
var models = modelBuilder(app, options);
Further inspection of models/index reveals following usage:
- get hold of
loopback
to callloopback.getModelByType
to auto-detectUser
andApplication
models to use - resolve dataSource from a name via
app.dataSources[name]
I would prefer to improve the middleware-registration process to support all three cases listed above instead of injecting the app
object.
from loopback-boot.
On the second thought, middleware factory should not setup models nor register other middleware. Instead, we should implement a new mechanism to support complex components like oauth2.
The component exports function(app, options)
, end-user configures components in a new file (component-config.json
?) and loopback-boot will invoke the functions exported by configured components.
This is most likely the item/feature that should have been implemented as part of #45.
