+# esm-import-transformer
+
+Can transform any ESM source code `import` URLs using an import maps object. This package works in ESM or CJS.
+
+```js
+// Input source code:
+import {html, css, LitElement} from "lit";
+
+// Transform with an import map:
+import {html, css, LitElement} from "https://cdn.jsdelivr.net/gh/lit/dist@2/core/lit-core.min.js";
+
+// Or transform to a dynamic import:
+const {html, css, LitElement} = await import("lit");
+
+// Or transform to CommonJS require:
+const {html, css, LitElement} = require("lit");
+```
+
+## Usage
+
+```js
+// ESM
+import { ImportTransformer } from "esm-import-transformer";
+
+// or CJS
+const { ImportTransformer } = await import("esm-import-transformer");
+```
+
+### Transform with an import map
+
+Pass in a source code string and an [import maps](https://github.com/WICG/import-maps) object.
+
+```js
+let sourceCode = `import {html, css, LitElement} from "lit";`;
+let it = new ImportTransformer(sourceCode);
+
+let importMap = {
+  imports: {
+    lit: "https://cdn.jsdelivr.net/gh/lit/dist@2/core/lit-core.min.js"
+  }
+};
+let outputCode = it.transformWithImportMap(importMap);
+// returns: `import {html, css, LitElement} from "https://cdn.jsdelivr.net/gh/lit/dist@2/core/lit-core.min.js";`
+```
+
+### Transform to dynamic `import()`
+
+```js
+let sourceCode = `import {html, css, LitElement} from "lit";`;
+let it = new ImportTransformer(sourceCode);
+
+let outputCode = it.transformToDynamicImport();
+// returns: `const {html, css, LitElement} = await import("lit");`
+```
+
+### Transform to `require()`
+
+_Added in v3.0.1_: This method does _not_ require that the downstream package is CommonJS, but remember that _running_ the resulting code will fail if you try to `require` an ESM package (in some JavaScript environments, e.g. Node < 20).
+
+```js
+let sourceCode = `import {html, css, LitElement} from "lit";`;
+let it = new ImportTransformer(sourceCode);
+
+let outputCode = it.transformToRequire();
+// returns: `const {html, css, LitElement} = require("lit");`
+```
+
+### Has imports?
+
+_Added in v3.0.2_ Returns true if the code has any top level `import`.
+
+```js
+let sourceCode = `import {html, css, LitElement} from "lit";`;
+let it = new ImportTransformer(sourceCode);
+it.hasImports(); // true
+```
+
+```js
+let sourceCode = `const {html, css, LitElement} = require("lit");`;
+let it = new ImportTransformer(sourceCode);
+it.hasImports(); // false
+```
+
+
