10.4 Submodules and utility functions

• Split your codebase into smaller pieces

• golem::add_fct("helpers", module = NULL) adds R/fct_helpers.R

• Organisation:

  • R/utils_ABC.R - small functions used throughout the app (Purpose-centered; eg, formatting)

  • R/fct_DEF.R - larger functions that aren’t module-specific (Topic-centered; eg, db access)

  • R/mod_XXX_[fct|utils]_YYY.R - functions relevant to a specific module

• golem::add_module(name = "xxx", fct = "yyy", utils = "zzz")
