Recursive Modules: Binding to external libraries

[YKW]

I’ve been making a Discord bot in rescript and in turn have been writing a lot of bindings for DiscordJS. DiscordJS is heavy on OOP, which has made it a bit painful.

I’e run into a dependency cycle error and am curious about the best way to solve it

// GuildMember

type t
@get external getGuildMemberRoleManager: t => GuildMemberRoleManager.t = "roles"

// GuildMemberRoleManager

type t
@get
external getGuildMember: t => GuildMember.t = "member"

As far as I can tell, the best option is flattening into one file, and then using aliases to separate modules into multiple files
Like this

Is there a better way? These bindings are rather large and it would be a shame to put it all in one file

There’s another thread that discusses a similar problem:

How do you deal with circular bindings references in sub modules?

If your modules are organized into files, then you will need to define your types in a separate file. // Types.res (or whatever you call it) type foo type bar // Other files: module Foo = { type t = foo @send external withBar: bar => int = "withBar" } module Bar = { type t = bar @send external withFoo: foo => int = "withFoo" } Recursive modules aren’t possible on the file level.

And worth noting that recursive module support may be removed in the future.
