8 Tips for Mastering Node.js
Node.JS

As one of the most popular open source platforms
for developing server applications, Node.JS has a
wider acceptance amongst the developers
community largely for its lightning speed and
diverse scalability have made it a preferred
choice for conceiving complex developments, ever
since it came into being in 2009. While an
enhanced focus on User Interface (UI) and User
Experience (UX) has helped achieve superlative
reach ability, heres how the developers could
upscale their product credibility following
optimal code practices to begin with.

Modularize Your Code

Modularize Your Code
Entangled in the habit of writing uncomfortably
long pieces of code? As working way out, organize
your code into smaller pieces that improve
readability for your and anyone elses later
reference. It may seem to be difficult, but
rewards of the same will show up later on. If you
cant do that, how could you expect anyone else
to do that? If you do that, you would find it
relatively easy to make most of Nodes
asynchronous philosophy. Keeping chunks of code
small will help you during the development of
complex applications in Node.JS.
5
Group Require Statements at the Top

Group Require Statements at the Top
This one is hugely recommended! Grouping
Require statements at the top to avoid
performance issues as Require is synchronous
and halts the execution. Instead, you could
utilize the in-built module loading system of
Node that has its own require function for
loading modules existing in separate files.
7
JavaScript Standard Style to the Rescue

JavaScript Standard Style to the Rescue

• Further, an absence of a set development style
  can lead to serious problems in the code later on
  and the same can be better avoided by opting for
  Javascript Standard Style. In this way, you would
  be spared of unnecessary complications and
  managing .jscsrc or .jshintrc files as well.
• Automatically format code by running standard
  fix, you can auto format code
• It is possible to save a lot of time by fixing
  programming errors and style issues early on
• For strings make use of single quotes
• Single space after keywords
• Function name followed by space

9
Use Asynchronous Code

10
Use Asynchronous Code
Input/output operations can be performed
synchronously (where the resources get blocked
for some duration) or asynchronously (where the
resources arent blocked and tasks can be
performed in parallel). However, if there are
multiple such operations where resources keep
getting blocked, the performance of overall web
application would be hampered significantly. The
Promise object and the Event Loop can prove to be
of immense help in this regard.
11
Semantic Versioning

Semantic Versioning
Have you ever thought that by updating packages
without SemVer you are already breaking up Node
apps! It is so important to use Semantic
Versioning to notify your customers about updates
and that what all tasks are required at their end
for updating to the new version.
13
Nip the Errors in the Bud

Nip the Errors in the Bud
Leaving bugs in the code can lead to ugly
scenarios, at times even after deployment. In
order to stay clear from causing total chaos
later on, make it a point to listen to error
events. In this way, you can spot an error at an
early stage and take corrective action
accordingly. Error handling is somewhat easy in
Node and you could make use of the same without
any major fuss.
15
Make Use of Containers
node.js
16
Make Use of Containers
Containers are essentially the way forward when
it comes to programming with Node. A container
like Docker can make your deployments immensely
secure, among other advantages. Besides that, you
could even simulate production environments
locally with the same.
17
Ensure Security, Above Anything Else
node.js
18
Ensure Security, Above Anything Else
Ensuring that your applications are completely
secure is the least expected from you as a
developer. There a number of useful applications
within Node such as Node.JS security, Data
Validation, Session Management, Brute Force
protection and so on.
19
Node.js
Node.JS Technology has proven to be an immensely
effective tool for solving a variety of problems
and that is precisely the reason why developers
happen to prefer it over other tools. Though its
difficult to resist the temptation, a quick
browse through the best practices will surely
help leap over possible inconsistencies.
