We are using NodeJS framework. I need to mock a dynamoDb insert function. I am not sure how to set this up and all the Google'd examples are for queries. Anyone help me out? Thank you.
Might be you need something similar to https://www.npmjs.com/package/dynamoose to connect nodejs and dynamoDB. This is a similar library to mongoose which is used for nodejs and mongodb connection. It just not only handles connection but it is an object modeling tool for Amazon's DynamoDB.
Look here for Put and batchwrite operations samples from AWS. The node.js ones are in the midst of moving from v2 of the SDK to the newer v3 AWS JS SDK.

We are currently using NodeJs with Knex for connecting with MySQL.
We have plans to migrate our database to Cloud Spanner.
So wanted to know, if knexjs has support for cloud spanner.
I did not see any related articles in their official website (http://knexjs.org/).
If not, any ORM which has support to both MySQL and Cloud Spanner which will have minimal changes from knexjs
We continued using Knexjs for our Spanner operations. It is working fine so far.
We build the queries using knex
and convert it to raw queries using
querybuilder.toSQL()
and binding the parameters.
The Google public docs list the different libraries that can be used with Google Cloud Spanner. You can use node.js with Cloud Spanner so I believe the knexjs should also work. A recommendation is to modify your code so that knexjs outputs the SQL command to help with debugging in case certain commands don't work
Actually I'm planing to use NodeJS for web application development, my back-end DB is Informix, I'm looking for the ORM framework which best fit for Nodejs and also supports DB Transaction. Previously I used MyBatis with JAVA and Spring I'm wondering whether it supports or not.
Also it is very helpful if someone can provide an example/sample implementation fro CRUD operation using Informix, NodeJS (with or with out ORM)
I searched google with no luck. Appreciate your help. Thanks In advance
Here are some examples in multiple languages (java, javascript, python, etc) to help you get started with app development against Informix backend - https://github.com/ibm-informix/informix-client-examples
Web app development against Informix should be greatly simplified since REST APIs are available for accessing data in relational tables as well as collections. Here is a tutorial on the Informix REST APIs - http://www.slideshare.net/BrianHughes70/informix-rest-api-tutorial
What is the best npm library for dynamodb? There are quite a few on npm.
Right now my production application is running with a mongodb and mongoose.
Now things are becoming simple in Dynamodb using schema based AWS dynamodb data mapper library in Node.js
For more details, have a look on following aws package.
Data Mapper with annotation
Data Mapper package for Javascript
Advantages of using Amazon Data mapper library
Library take cares of Data marshaling
Schemas will be mapped to Javascript class entities
Similar to ORM
Developed by Amazon
There's a couple of good ones:
vogels and
dynamite
I'm using Vogels in my app at the moment, I like that it gives an extra layer of protection over your database via a Joi Schema, though it's not maintained as actively as you might like.
Dynamite is promise based and built by Medium, so it's worth a look as well.
What is the best way to provide code samples for my NodeJS application that uses mongo via mongoose.
I am dealing with a problem where I want to post a working example of some schemas & models that requires DB access.
I was hoping for something like jsfiddle but could not quite figure out how to use that for what I wanted.
Yes, I'm a noob... Thanks!
Why don't you try the reliable service of c9.io?
I haven't tried using Mongoose there, but it shouldn't be much of a magic.
I'm new in Node.js. I'm trying to find out and learn which is the best way to set an Api Server, just for CRUD (Create, Read, Update and Delete) requests.
I've being looking around the different server frameworks that are normally used with Node.js:
Express
Restify
Hapi
I'm also using the node-postgres library already connecting to the database and making queries, but I haven't found a good guide or example using either of the previous frameworks to set an Api Server with PostgreSQL.
I'd be very thankful is someone could point me to the right direction or show me a basic example.
Thank you
Hapi has the best performance. Otherwise I hope this can help you:
