Creating a new database using NPoco - npoco

I'm trying to create a database using NPoco. I would like to know how I could do that ? Please list out the ways to create/initiate Database in Npoco .Thanks in Advance

You don't. Npoco is not responsible for creating the database and scheme etc. It's a micro orm for querying and mapping.
You need to script off your database yourself.

PostgreSQL + Node Integration

Need some advice regarding the following situation:
There is an existing PostgreSQL database that I would like to draw information from (with full authorization of course). How can I query the entries in that database using NodeJS? I know sequelize can offer what I'm looking for, but I'm a bit confused as to how to approach this. I've heard that I would have to migrate the data first in order to then query it. What's the best way to go about doing this? Thanks.
For reference, I've taken a look at this link (https://github.com/sequelize/sequelize/issues/3791) but haven't gotten what I'd hoped out of it.
You can query without migration for existing database, this package should help https://www.npmjs.com/package/pg

DB-agnostic Node.js code

I have some node.js code that connects to CouchDB and now I'm exploring other NoSQL databases (DynamoDB, MongoDB, etc).
Is there a DB-agnostic module that would allow me to switch NoSQL databases without much trouble?
For sure you will need to change your code to adapt to a new database.
Anyways, there are a few options that allow you to switch from one of other database easily.
If you consider building from scratch, Loopback has a juggler that allows to setup each model to connect to a different database. If you want to include it as a module in your app. probably you are looking something like Waterline.
I have only used Loopback, it's great.
I haven't used Waterline.

Arangodb Accessing database A Collection in database B

I am trying to access one database collection in a different database. Is it possible in arangodb.
Regards,
Sajeev
No, its not possible.
ArangoDB strictly separates databases, so AQL doesn't know about databases in first place, its concept is below the database layer.
As we also discussed in the github issue we actually don't intend to implement support for this.

list all the databases and tables in nodejs either using loopback-datasource-juggler or jugglingdb

I am developing an strongloop-arc like tool on loopback (nodejs). To discover models from existing data-sources I need to list all databases and there tables to the user, from where user will select database and table to discover model.
What should I do to achieve the above requirement.
I found answer of my own question from here
https://docs.strongloop.com/display/public/LB/Database+discovery+API#DatabasediscoveryAPI-discoverModelDefinitions
from here I can discover all tables of database by giving database as parameter.

Two nodejs applications, one mongodb database

Good day! I have created an application using nodejs + mongoose and now I want to make something like a superuser application. I need my admin panel application to connect to the same database. So, i have a question.
Should i store the same Schema file in both applications to have an ability to use my Schema methods? In other words, what is the best way to create one more API using the same db?
Thank you!
If I'm not mistaken, why not create another service that only interacts with the database? That way, the systems will refer to the same schema/DB regardless of which application you want to connect to it. So the superuser application and the normal application will just query the DB microservice that interacts the database.
Pro: source of truth for the schema for all applications and the DB queries will just be API calls
Con: additional overhead in creating your ecosystem
If you are using the same DB from two different applications, you will want to make sure those schemas are the same between the two. If one changes its inputs, the other might need to change its display (or risk not expecting all that information). Keep all this in mind during your release process.
I would suggest making the schemas an external library to both, or have the admin panel require the current app. You'll avoid getting two sets out of sync and know to look at one place for the schema definitions.
