This is a project with ReasonML bindings for date-fns v2. These bindings are using FP module of date-fns. So please refer the FP documentation. In short: all methods are curried and date value is always last argument (|>).
Tip: On date-fns documentation you can choose
submodulein the top right corner and view documentation and function signatures just like you would use it in reason. Here is an example ofFPsubmodule docs page.

Simple example:
open ReasonDateFns;
Js.Date.make()
|> DateFns.addDays(2)
|> DateFns.addDays(-2)
|> DateFns.closestTo([|
DateFns.parseISO("2019-08-21T13:00:03.058Z"),
Js.Date.make(),
|])
|> DateFns.lightFormat("YYYY-MM-DD");
Js.Date.make()
|> DateFns.formatWithOptions(
DateFns.formatOptions(~locale=DateFns.Locales.ru, ()),
"YYYY-MM-DD",
);
Js.Date.make()
|> DateFns.addMinutes(10.)
|> DateFns.addSeconds(10.)
|> DateFns.addMilliseconds(1000)Have a fun with FP 👨💻
Make sure that you need date-fns v2.
yarn add reason-date-fnsAnd add reason-date-fns to your bsconfig.json
{
"bs-dependencies": [
"reason-date-fns"
],
}There are 2:
1) This project is exporting to date-fns of v2
2) And using FP submodule. So currying is enabled by default 😎
