Getting started

Start by importing this package and DataFrames.jl:

using BoardGameGeek
using DataFrames

We can query the reviews a specific user wrote via userreviews(username)

julia> user = "bggjulia"

julia> DataFrame(userreviews(user))
4×5 DataFrame
 Row │ id      name                       username  rating   comment 
     │ Int64   String                     String    Float32  String  
─────┼───────────────────────────────────────────────────────────────
   1 │ 140934  Arboretum                  bggjulia      9.0

   4 │ 256960  Pax Pamir: Second Edition  bggjulia      9.0

or simply use collection get the game IDs of their collection

julia> collection(user)
4-element Vector{Int64}:
 140934
 225694
    188
 256960

Game reviews

Use gamereviews(id) to scrape all reviews that were written for a specific game

julia> DataFrame(gamereviews(188))

Note that this can take a while for games with many reviews, as we don't want to run into the BoardGameGeek API rate limit. The default wait time of 2 seconds per 100 reviews can be changed via the keyword argument waittime.

Full game info

Use gameinfo(id) to obtain all sorts of information about a game. A summary of all data is given in the reference below.

GeekBuddies

Finally, we can also take a look at "GeekBuddies" and user profiles via userinfo(name):

julia> buddies(user)
2-element Vector{String}:
 "Aldie"
 "dakarp"

julia> DataFrame(userinfo(buddies(user)))
