# Stream out

stream_out(df, con)
close(con)

# NDJSON (newline-delimited)
stream_in(file("data.ndjson"))
stream_out(df, file("output.ndjson"))

API Requests

# GET request
data <- fromJSON("https://api.example.com/data")

# With httr
library(httr)
resp <- GET("https://api.example.com/data")
data <- fromJSON(content(resp, "text"))

# POST with JSON body
resp <- POST(
  "https://api.example.com/data",
  body = toJSON(list(key = "value")),
  content_type_json()
)

# Validate JSON
validate('{"valid": true}')  # TRUE
validate('{invalid}')        # FALSE
