• 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
• 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.
• 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.

• 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
• 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.

• 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.
• 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.
• 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.

• 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.
• 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.
