If You Have Two Truths, One Is a Lie

Always maintain a 𝘀𝗶𝗻𝗴𝗹𝗲 𝘀𝗼𝘂𝗿𝗰𝗲 𝗼𝗳 𝘁𝗿𝘂𝘁𝗵 (𝗦𝗦𝗢𝗧).

It means 𝘀𝘁𝗼𝗿𝗶𝗻𝗴 𝗮𝗻𝘆 𝗽𝗶𝗲𝗰𝗲 𝗼𝗳 𝗱𝗮𝘁𝗮 𝗶𝗻 𝗼𝗻𝗲 𝗽𝗹𝗮𝗰𝗲, 𝘄𝗶𝘁𝗵 𝗮𝗹𝗹 𝗼𝘁𝗵𝗲𝗿 𝗿𝗲𝗽𝗿𝗲𝘀𝗲𝗻𝘁𝗮𝘁𝗶𝗼𝗻𝘀 𝗱𝗲𝗿𝗶𝘃𝗲𝗱 𝗳𝗿𝗼𝗺 𝘁𝗵𝗶𝘀 𝗽𝗿𝗶𝗺𝗮𝗿𝘆 𝘀𝗼𝘂𝗿𝗰𝗲.

This concept can save you a lot of headaches.

Here’s what it looks like in practice:

APIs: Keep a single, authoritative document for all your APIs.

Learning: Use one central database for all your knowledge on a specific subject.

Environment: Use one configuration file for setting up all your development environments.

Why does single source of truth matter?

In software development, multiple sources of truth often lead to synchronization bugs and data inconsistencies.

𝗜𝗳 𝘁𝗵𝗲𝗿𝗲’𝘀 𝘁𝘄𝗼 𝘀𝗼𝘂𝗿𝗰𝗲𝘀 𝗼𝗳 𝘁𝗿𝘂𝘁𝗵, 𝗼𝗻𝗲 𝗶𝘀 𝗽𝗿𝗼𝗯𝗮𝗯𝗹𝘆 𝘄𝗿𝗼𝗻𝗴.

𝗜𝗳 𝗶𝘁’𝘀 𝗻𝗼𝘁 𝘄𝗿𝗼𝗻𝗴, 𝗶𝘁’𝘀 𝗻𝗼𝘁 𝘄𝗿𝗼𝗻𝗴… 𝘆𝗲𝘁.

So don’t read multiple pages.
