Tutorial Series One: Data Brokering with Node.js

While data brokering can take many forms, it ultimately tries to solve the problem of moving data between different systems — a perfect task for Node.js. This can be done using a thin proxy API, an ETL (Extract, Transform, Load) pipeline, or a message queue. In our first course, we evaluate and write code using all three methods. We’ll also help you choose the right one for your project.

More Data Brokering with Node.js tutorials are coming soon!

What Is Data Brokering?
Often we have data available in one system and we want to work with it in a different system.
Overview: Node's Module System
Modules allow developers to better structure, reuse, and distribute their code.
What Is NPM?
Working with Node.js means we have a flourishing ecosystem of open source software and tools available to us.
Free!
What Is package.json?
Node projects keep track of dependencies and metadata in a special file named package.json in the root directory of the project.
Free!
Create a package.json File
If you're starting a project from scratch, you'll need to create a package.json file to hold important metadata about your project and record your dependencies.
What Is package-lock.json?
You may have noticed it before; you install a package using npm and suddenly a new file called package-lock.json appears in your project directory.
Install NPM Packages
Installing packages and dependencies is one of the most important tasks we accomplish using the npm Command Line Interface (CLI).
Uninstall Packages from a Project
Removing a dependency from a project is a 2-step process.
Free!
What Is Semantic Versioning (SemVer)?
The NPM ecosystem uses Semantic Versioning as the standard for version numbers.
Update a Dependency
It's important to keep your dependencies up-to-date.
What Are NPM Scripts?
An npm script is convenient way to bundle common shell commands for your project.
Restart Applications upon File Changes
We can create a custom npm script to run our project during development.
Free!
ETL Pipeline: What Are We Building?
In this series of tutorials we are going to learn about using Extract, Transform, Load pipelines for moving and processing data between systems.
Free!
What Is an ETL (Extract, Transform, Load) Pipeline?
ETL is a process of extracting data from one location, transforming it in some way, and then loading it somewhere else.
What Are Promises?
Promises make writing asynchronous code easier.
Wait for Multiple Promises
Sometimes we to need to execute multiple asynchronous operations concurrently, wait for them all to complete, and then do something with the combined result.
Use Async/Await with Promises
To write asynchronous code in a way that reads like synchronous code, we can use async/await, a feature in JavaScript.
Make API Requests with request-promise
Making HTTP requests to an external API from a server is a task you'll encounter often.
ETL: Extract Data
We will be creating the extract step in our ETL pipeline to extract the data we need from the data source.
ETL: Transform Data
Once we have the payload from our service, we can transform the data into the format we want the data in.
What Is the fs (File System) Module?
To read data from a file, we use the built-in node module fs which helps us work with the filesystem of the computer running our code.
Free!
Read/Write JSON Files with Node.js
When you want to store data between server restarts with Node, JSON files are a simple and convenient choice.
ETL: Load Data to Destination
After you have extracted and transformed your data, the final stage of an ETL pipeline is loading the data to the destination.
What Is a Stream?
Streams are a built-in Node language feature that represent an asynchronous flow of data.
Use Streams to Extract, Transform, and Load CSV Data
Using the fs module and streams, we can take a local file and perform ETL steps on it to transform the file into JSON and write it to disk.

Through community surveys and interviews, we’re learning how to connect our tutorials with what our members want to learn:

How do you use Node.js?

How do you learn Node.js?

“When I discover I don’t know enough about something, I consume as much knowledge as I can."

“Node for scripting is a way for us to do simple things in a lot of different places really quickly like setting up new clients or changing subscriptions.”

“Everyday learning is part and parcel with being a developer.“

“My ideal learning resource entails short-form videos with in-line code tidbits - something that won’t go out of date in a month.”

“The best learning is when explanation and practical knowledge go hand in hand.”

“A lot of tutorials tell you what you need to fix, rather than explaining why it fixes it or how you went wrong.”

"I never approach learning open-ended. I have to have a problem I'm trying to solve.”

“I typically learn under duress. Something is breaking and I need to learn how to fix it. After that, I hope I get the chance to practice.”

“Learning how you learn is super important. I like to know the naming system of a framework or technology because then I can talk about it.“
