Hi Forest,
How should we import a model in a TS file using the new database configuration?
Here is how we created models:
Should do something like this ?

I’m not very found of that …
Hello @Guiguijo 
First of all, I just want to let you know that I’m currently working on new types for our repository forest-express-mongoose version 7 
. They should be available this week, latest would be next week.
I have run into the same issue as yours. The best workaround I have found so far, is to put your models under db.models and export it alongside objectMapping and connections.
Then, wherever you need a model you could do the following (similar to your suggestion):
import { models } from '../models';
const Accounts = models['accounts'];
From there, and with the new types incoming, you will benefit from the typescript system and auto-completion from mongoose.
I’m not a big fan of this as you mentioned. Sadly, due to dynamic model imports I have not been able to find anything better so far.
If you have any suggestion, as I’m currently working on typescript projects/types for lianas version 7, I would be really glad to get them.
I hope this helps out,
Steve.

when starting the project in TS with the new DB configuration I can see some wired logs:
Model creation error: SyntaxError: Unexpected token ':'

It seems that some errors are raising in a first time but they disappeared.
Have you encounter the same case ?

I think the problem of
Model creation error: SyntaxError: Unexpected token ':'
comes from the file-name.js.map that are produced by Typescript in the /model folder.
I added a condition in the function that filters the model files in the index.ts to avoid those files:
fs.readdirSync(modelsDir)
.filter(file => file.indexOf('.') !== 0 && file !== 'index.js' && !file.includes('.map'))
...
Hello @Guiguijo
I am glad to announce that the new Types implementation has just been released 
To benefit from the new Types, you just have to upgrade your Liana to version 7.9.0. Yes, Types our now directly integrated in the forest-express-mongoose repository, you don’t need to install @types/forest-express-mongoose anymore 
To help you with your migration, we also created a documentation to guide you as much as possible, please refer to this link.
Don’t hesitate to post any issue or frustration you encounter regarding Types, we will be glad to help you out and every feedback are appreciated.
I hope you will enjoy the new version !
Steve.

(just above your last post )@Guiguijo yes I did. The documentation has a section about it.
For the mongoose version of forest-express we decide to go from a dynamic loading approach to a static loading (please refer to this section of the documentation).
But indeed, I have your comment into account for the sequelize version (which still uses dynamic loading) and I thank you for it 
Steve.
