In general what's the difference in dev. vs staging part of website?

Question

What's code wise the difference between dev and staging fase of a website?

I mean dev <-> live, than live all code is clean/minimized, right?

Any info, real life "code" part examples?

Answer 1

dev

• No compressed/minified/etc. code
• Likely to be separate for each developer
• Not updated from VCS but the code that resides there is committed at some point
• May contain not-working code (usually yet uncommitted)

staging

• Updated from VCS
• Should have the exactly same setup (lib versions etc) as production
• Testing setup for code that is supposed to go in production
• Some code is likely to be minified to see if it breaks anything.

production

• Well.. production ;)
