Thank you so much!

Thanks for the feedback!

Thank you so much!!

You're welcome !

Thank you!

I'm gonna make a video covering request scope vs the default scope, hopefully it helps you out!

@@Computerix That sounds interesting.

I'm planning on doing so sometime this year! Just to be clear, authentication handling, specifically in multitenancy, correct?

@@Computerix yes exactly, registration, login, interaction between the User and Product table for example to know which user created a particular product

@@burnsnewman I haven't looked in to it, but the durable provider suggestion is a good one !

Hello, Please, have you implemented such an architecture that connects several models with mongoose or prisma ?

@@mohsensareminia2988we could have done that! Good point

Tokens that are injected that represent a provider are unique, so as a first thought I'd say yes, you need to create a provider for each model. I haven't really thought of workarounds or of ways to make something generic work. If you have done that in the past day, let us know!

I'm glad my videos are helpful! I am going to create an authentication video for multitenancy soon, meanwhile feel free to watch this authentication video that I uploaded a week ago : kzfaq.info/get/bejne/npNma9ai3d_Heo0.htmlsi=VeiWno8dL0UA2ike It's going to be similar, except we're gonna be using different secret keys for different tenants (these keys would be stored in the database)

@@Computerix Okay, looking forward to your new videos.

Sadly, as per the mongoDb documentation (www.mongodb.com/docs/manual/reference/operator/aggregation/lookup/), lookup only works on collections within the same database. However, you can create multiple queries (each query could be on a seperate database) and merge the results yourself. To fetch results from the master database : 1- Simply register the model like we normally do using MongooseSchema.forFeature. (This works, since in app module our default connection is pointing to the master DB) 2- Inject the model using the normal @InjectModel(). This model will point to a collection in the master DB. To fetch results from the tenant specific database, inject the custom tenant model provider like in the video :) ..and then manually merge the results

It depends. If you are trying to fetch some data specific to a tenant (so it exists inside the tenant specific Database) for example a list of products being sold by a tenant, you need the frontend to specify the tenantId in the headers (Also it's a best practise to sign each user token with a tenant-specific secret for security purposes) that way, you know where to connect and what data to fetch. However, if a user is trying to login, they send their credentials only. To tell which tenant they belong to, you can store the tenantId inside the users table. So in summary, it depends on the requirements, but for most cases, the frontend would need to send the tenandId in the headers. Hope this helps :)

@@Computerix Thank you so much for the reply! I just had a meeting with my company and we decided to go with the tenantId in the headers approach. u helped me alot and this video will help me through implementing it in nestjs, making my task easier :D (please dont remove this video lol) 1 thing we were not sure about is how we can have 1 front end server deal with 2 different domain urls, my company just started implementing custom solutions so we are trying our best, do u know how its done? Thanks alot!

@HamoudyMulti hmm, can you explain your question more?

@@Computerix I have another question after going through ur video. im currently using a RDS with MS SQL and sequelize ORM. I couldnt apply most of the things in the video, as sequelize doesn't allow u to change database within same connection like in mongoose (in ur videos its the useDB method). do u think its a good idea to create all the connections at once when initiliazing the application for all tenants? or initialize the connection on each request for a given tenant? the number of tenants is not that high (3 or 4 max), although im not sure what is the best practice. thanks again for ur great help!

​@@HamoudyMulti I haven't used sequelize before, so i'm not very familiar with it. But what you can do, is check if you have an existing connection to a certain tenant DB, if that's the case, use it. If not, create it and use it for the current and future requests for that tenant. The key, is managing the connections in a clean way. So make sure to reuse existing connections :))

Thanks!

Can you please cover the topic of dockerizing a nest app and the cloud usage suggestions etc, that would be a great video, thank you!@@Computerix

I'm glad ! The link is in the description : github.com/charbelh3/NestJs-Multi-Tenancy

@@Computerix you are my angel😍

Thanks for your comment! Yes that's correct.

Thanks for the feedback! I think it's best if you avoid creating a collection per tenant. Instead go for 1 single database and 1 products collection for all tenants, and create a field named "tenantId" inside the same collection to know which document belongs to which tenant, if you don't want to use the database per tenant approach. (refer to stackoverflow.com/questions/2748825/what-is-the-recommended-approach-towards-multi-tenant-databases-in-mongodb and web.archive.org/web/20140812091703/support.mongohq.com/use-cases/multi-tenant.html)

Thank you! This is my linkedin: www.linkedin.com/in/charbel-el-helou-6523a5200/

@@ChetanSharma-jy8om If you have such a use case, it's better to keep a copy of the newly created products in your main database (the default mongooseModule that you register), that way you fetch them all from the same DB

@@ComputerixOne last thing from your side , As you are creating dynamic dbs in mongo db Is there as such limit for them.Because I am using managed mongodb by digital ocean

Thank you for the comment! Here is the code: github.com/charbelh3/NestJs-Multi-Tenancy

Thanks 😁

Hello! I was thinking of making a discord community server.. but at a later time. In the meantime, feel free to tell me your concerns here :)

I have one project I want to discuss it with you via another channel. Appreciate if you can tell me how to reach you. I added my contact here many times but it's deleted Thank you

​@Computerix I have one project I want to discuss it with you, So please tell how to contact you. I am trying to put my contact here but it always deleted
