docs incompatible with function namespaces

As a new user it is totally unclear, which functions are available in the main turf package, and which functions need to be separately loaded in external packages:

After some lengthy experiments it seems to me, that all functions listed in the docs are included in turf, except for the ones in section Meta. These can be called on the package turf-meta. Except for turfMeta.getCoord() which is nonexistent in the code it seems. instead the function turfMeta.coordAll() is available, but listed under Assertions in the docs…?!

So there is definitely some clarification needed:

• what functions can be used by default
• what functions need to be loaded separately
  • from which package
• a list of external packages
• a best practice to add functions from external packages to the turf namespace

edit: I’m using the latest npm packages turf@3.0.6 and turf-meta@3.0.1

I believe this could now be marked as closed given the recent updates to the docs, I hope they are much clearer in this regard. cc @DenisCarriere

Diagnostics

I would need a feedback on the current state I discovered for then contributing.

In the docs

… …

• META
  • propEach (1) (turf-meta)
  • coordEach (1) (turf-meta)
  • coordReduce (1) (turf-meta)
  • featureEach (1) (turf-meta)
  • getCoord (1) (turf-invariant => wrong in the doc?)
• ASSERTIONS
  • featureOf (1) (turf-invariant)
  • collectionOf (1) (turf-invariant)
  • bbox
  • circle (1) (turf-circle => wrong in the doc?)
  • geojsonType (1) (turf-invariant)
  • propReduce (1) (turf-meta => wrong in the doc?)
  • coordAll (1) (turf-meta => wrong in the doc?)
  • tesselate

(1) Not in default turf.min.js

Conclusion:

META

Quite consistent except for getCoord in turf-invariant and propReduce and coordAll in ASSERTIONS…

ASSERTIONS

• bbox and tesselate are not related to turf-invariant but provide by the default turf build
• circle has it own package
• some assertions are in turf-meta, some other in turf-invariant => consistency choice?

In the code

Missing doc in official site (need confirmation):

• turf-center-of-mass
• turf-line-slice-along
• turf-idw
