Working with Sitecore can be challenging for developers that are new to the ecosystem. However, the kinds of projects you'll be able to work on in the future have a good chance of being interesting 🤔, challenging 😬, rewarding 🏅, and even 💎prestigious💎 by nature of the types of clients that use Sitecore (medium to large enterprises). Over the years I've had the privilege of working on massive websites for many recognizable brands and organizations.

Enjoy some of my favorite tips and tricks.

Content Editor Tips

Use Navigate -> Find links

Read the damn error messages (console log, sitecore log, event viewer, IIS logs, etc.)! Do your own searching before asking for help. Refine what the problem actually is.

The fastest way to locate backend code is to start with the frontend by using the browser dev tools and finding unique strings that identify certain areas

Speed Running

Speed running overview

Concept of speed running — reduce the build and startup times with configs, PC optimizations, optimize compilations, view compilation vs not for speed, comment out major areas of the site that are not applicable such as headers, footers, etc. You can also use unit tests to speed up development time since you won't be waiting for Sitecore to warm up.

Find ways to speed up your build cycles. Here's one approach.

Use master as your web DB so you don't need to publish.

LiveMode.config.example:

<!--
Purpose: This include file enables live mode, so that data is read directly 
from the master database, thereby bypassing the need to publish
To enable this, rename this file so that it has a ".config" extension
Notice how "patch:attribute" is used to change the value of attributes that 
are specified for an existing element in the web.config file
-->
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
  <sitecore>
    <sites>
      <site name="website">
        <patch:attribute name="database">master</patch:attribute>
        <patch:attribute name="filterItems">true</patch:attribute>
        <patch:attribute name="enableWorkflow">true</patch:attribute>
      </site>
    </sites>
  </sitecore>
</configuration>

When in doubt, start with a fresh install. Get really good at installing new instances of Sitecore. Compare and contrast vanilla settings / configs with your own.

Look at the config examples in App_Config/Include/Examples

Certifications

Swallow the frog! Stop asking people for tips and how hard the test was. Carefully read the breakdown of testable subjects, do the preparation that Sitecore recommends, and let it rip. Sitecore partners get discounts on exams. Partners need certified developers to retain their partner status. Take advantage of this.

TODO: meme certificate

As a new Sitecore developer, you need to have a good understanding of templates, workflow, renderings, rendering parameters, etc. Getting a Sitecore developer certification is one of the best ways to learn.

Get really good at describing your issues with great detail so you can post them (or search for them) on Stack Exchange or in Sitecore Slack. I can't tell you how many times people in the community have saved my ass because I was able to adequately describe my issue. Point is, provide as much info as possible. Versions, logs, code samples, what you have already tried, which resources you have already read

Get really good at google searches - exact match keywords If you can't find results, either you're not looking for the right thing, or you are having an issue that's highly specific to your environment. It might be broken because of browser extensions, network restrictions, human error

Modify your view settings — not showing standard fields speeds up loading

Sitecore ribbon view settings

Use the gutter Content Editor gutter

Keep backups of your App_Config, bin, and Views directories for quick restoration.

Use Sitecore search for item IDs / names - rebuild indexes and link databases

if you see an item that has no links to it, that doesn't mean it's not used -- check the code for references to the ID / Path / item name.

Sitecore Best Practices

Never modify default Sitecore configs. Always use patch configs.
Get familiar with the Helix recommended practices and conventions -- it will help you understand implementations and make you a better developer.

Analysis & Problem Solving

Assume that NOBODY knows what they want and that any analysis, designs, or requirements are only preliminary. It takes too long to do analysis and so most projects just start with a general direction. It's up to you to flag details and work through them with the clients.

RFM — seriously, read the docs before you dive in.

There are many ways to solve problems, especially in Sitecore. The most powerful feature of Sitecore is its ability to be customized.

Get good at coming to understand a codebase. Think of what you know and don't know as a tree. If you are looking at a leaf, follow the branch until you locate the trunk Learn the Hot-Path Internals Trace down Learn up

Organization

Use checklists as you're working through problems.I have some great examples in my Bulletproof Components post series.

TODO: add more?

Coding

Always check for null values. Good Sitecore developers know how to code defensively.
Work incrementally — don't make too many changes at once.
Only refactor code if you 1) fully understand it, and 2) need to do so as part of the functionality that you're working on. I've seen many situations where me or someone else made an "improvement" to the code, only to find it cause many more issues in QA / upstream environments. Stay focused on the problem you're trying to solve.

Troubleshooting Sitecore Errors

Understand what is relevant in the logs and what is noise

If you see a lot of errors in the logs, that's a good indication that you should fix that ASAP before working

Always look in the logs first by searching for "ERROR " and "WARN " (note the space at the end).

If there are no logs at all, it's probably a web.config issue.

Programs & Tools

Set yourself up for success. Here are the tools I use:

NotePad++ (for editing and searching directories for text)
dotPeek (for decompiling)
VS Code
SourceTree
BeyondCompare (TODO: learn to use this for directories AND files)
SCLA
SIM (Sitecore xxx Manager)
BROWSER EXTENSION?

Always launch all programs as an Administrator. Here's a way you can automate it so you never forget.

Right click the program in the task bar
Right click the application
Click Properties
Click the Shortcut tab
Click Advanced...
Check Run as administrator

Always launch as admin

Personal Growth & Mentorship

Get a mentor

Link to the MVP Mentorship Program

Start a blog — teaching others helps you learn

Join Sitecore partner agency for exposure to many different clients / projects

Visual Studio Tips

If you see a chunk of code that has 0 references, that may not be true as the reference may be specified in an item or a config

Turn on the setting to show you the current file you're viewing in the Solution Explorer

Keyboard shortcuts :

CTRL + T (quickly navigate to files) CTRL + G (go to line) CTRL + F (find text) CTRL + M, CTRL + G (go to controller) CTRL + K, CTRL + T (view call hierarchy) CTRL + K, CTRL + D (reformat indents)

Solution —> Find All

Find all references Go to definition Go to implementation

Learn how to decompile code.

PowerShell Extensions

If you ever need to perform repetitive or analytical administrative tasks, Sitecore PowerShell Extensions (SPE) will help you automate it and do it faster. SPE is very powerful, and having a good understanding of it will set you apart from other SC devs.
