cool

 also, first

lol

I am unable to find this in my spellbook cards (Arcane). Is this just me? It is the official version. 

It's not in the spellbook cards because this is part of Xanathar's Guide to Everything, published after the cards.

When using this spell outside of battle, how malleable is the area of effect? For instance could i create a letter shaped fire if the over all volume was still 5 ft cubed?

Beyond the 5 ft does it creat heat or light?

Ouch!

Useless out of combat as is.

I would house rule it to be as written when casted in combat. When casted outside combat it would last 2h. Only one can exist at a time.

Enough for the camp

Ignites Objects that are not being worn or carried, if you are casting it on a pile of wood, then it creates a campfire/bonfire, otherwise its just making a large magical flame that sits there

You could could use this spell, and have someone else use Booming Blade to force an enemy into a lose/lose situation.

maybe use control flames intead?

 You’re supposed to use it to light fires not make a long lasting campfire. 

I love low level spells sometimes, they just feel so alive and immersive... Instead of those spells with huge explosions and dazzling effects. Yes they’re cool, but they don’t feel comfy. 

imagine you’re on a long journey, tired and cold. You ride off the dirt road to make a camp in the forest. You sit down, and your Dwarf friend Jorvad casts “Create Bonfire” over a pile of sticks. You stick your hands out to warm them up, and slowly... you drift off into sleep... 

So here's a zone question that I can't find any answer to, triggered by this spell:

I cast this on one square of a Giant Spider's 4 square token in LMoP last night.  Call it the upper left square.  Then the giant spider moved north one square, so now the fire is on its lower left square.  Did this count as entering the zone for the first time that turn (since a different part of its body moved into the sqaure)?  Or was "the creature" already "in" the zone, so no effect?  [For speed, we ruled "no effect" and moved on.]  The spider continued its movement north, so no, it did not end its turn with any part of its body in the Created Bonfire.

I presume the spider made a saving throw at the moment the spell was cast, and your question is whether it needs to make a second saving throw. Per the text of the spell: "Any creature in the bonfire’s space when you cast the spell must succeed on a Dexterity saving throw or take 1d8 fire damage." (emphasis added)

Presuming the spider made a saving throw when the spell was first cast, I would agree with the ruling of your table. The only time it would make a second saving throw is if it ended a turn with part of its body still in the square, or if it completely left the area of the bonfire and later entered that square again. It doesn't sound either of those happened, so no need to roll a second saving throw.

One way this thing's decently strong is in how it occupies space. Half of a 5' cube is enough to cause damage, so it can threaten anyone passing through a 10' wide corridor or be cast directly between 2 adjacent creatures.

Check with your DM on whether or not spells or effects snap to squares on a map. If so, this trick will not work.

Could one send a wood chip into an enemy, and cast create bonfire inside them?

Asking for a friend...

how big is a five feet cube?. It's only affect  a square on the grid?

 Yes, that's correct.
