Features

• #1114 Added JS.Import, JS.ImportDefault, JS.ImportAll, JS.ImportDynamic functions. Sample usage:

  [<Inline>]
  let importTestJsAll : obj = JS.ImportAll "/modules/test.js"
  // translates to: import * as test from "/modules/test.js"
  
  [<Inline>]
  let importTestJs : obj = JS.Import("testExport", "/modules/test.js")
  // translates to: import { testExport } from "/modules/test.js"
  
  [<Inline>]
  let importTestJsDefault : obj = JS.ImportDefault "/modules/test.js"
  // translates to: import def$test from "/modules/test.js"
  
  // this does not add an import statement on top of the file as the others, but uses JavaScript import function
  [<JavaScript>]
  let testImportDynamic : Promise = JS.ImportDynamic("/modules/test.js").Then(fun testModule => testModule?testExport())
  // translates to: import("/modules/test.js").then(function (testModule) { testModule.testExport(); })
  

• #1070 The javascript import function can now be used within inlines, translates to JS correctly.

  [<Inline "import('/modules/my-module.js').then(function (module) { module.run(); })">]
  let runMyModule() = X<Promise>
  

• #1120 Updated to FSharp.Compiler.Service 37.0. Building for net5.0 target framework and using FSharp.Core 5.0 is possible but no F# 5 language features are available yet.

Fixes

• #1115 WebSharper.InterfaceGenerator helper function Pattern.OptionalFields uses the original target JS name, does not appends Opt incorrectly.
• #1008 uint8 and uint16 array literals are now translated without compiler error.
