* `bundle()` is part the compiler API. A full description of this functionality
|
|
* can be found in the [manual](https://deno.land/manual/runtime/compiler_apis#denobundle).
|
|
*
|
|
* Takes a root module name, and optionally a record set of sources. Resolves
|
|
* with a single JavaScript string (and bundle diagnostics if issues arise with
|
|
* the bundling) that is like the output of a `deno bundle` command. If just
|
|
* a root name is provided, the modules will be resolved as if the root module
|
|
* had been passed on the command line.
|
|
*
|
|
* If sources are passed, all modules will be resolved out of this object, where
|
|
* the key is the module name and the value is the content. The extension of the
|
|
* module name will be used to determine the media type of the module.
|
|
*
|
|
* ```ts
|
|
* // equivalent to "deno bundle foo.ts" from the command line
|
|
* const [ maybeDiagnostics1, output1 ] = await Deno.bundle("foo.ts");
|
|
*
|
|
* const [ maybeDiagnostics2, output2 ] = await Deno.bundle("/foo.ts", {
|
|
* "/foo.ts": `export * from "./bar.ts";`,
|
|
* "/bar.ts": `export const bar = "bar";`
|
|
* });
|
|
* ```
|
|
*
|
|
* @param rootName The root name of the module which will be used as the
|
|
* "starting point". If no `sources` is specified, Deno will
|
|
* resolve the module externally as if the `rootName` had been
|
|
* specified on the command line.
|
|
* @param sources An optional key/value map of sources to be used when resolving
|
|
* modules, where the key is the module name, and the value is
|
|
* the source content. The extension of the key will determine
|
|
* the media type of the file when processing. If supplied,
|
|
* Deno will not attempt to resolve any modules externally.
|
|
* @param options An optional object of options to send to the compiler. This is
|
|
* a subset of ts.CompilerOptions which can be supported by Deno.
