importMap programmatic implementation

Introduction

jsenv-import-map implements importMap in native js. It is used by jsenv to use importMap even if they are not yet supported.
— see importMap spec

It has the following exports

• applyImportMap
• composeTwoImportMaps
• normalizeImportMap
• resolveImport
• resolveSpecifier
• wrapImportMap

resolveImport

takes { specifier, importer, importMap, defaultExtension } and returns an url.

import { resolvePath } from "@jsenv/module-resolution"

const importUrl = resolveImport({
  specifier: "../index.js",
  importer: "http://domain.com/folder/file.js",
  importMap: {
    imports: {
      "http://domain.com/index.js": "http://domain.com/main.js",
    },
  },
})

console.log(importUrl)

The code above logs http://domain.com/main.js.
