esbuild plugin for Syndicate/JS

import esbuild from 'esbuild';
import { syndicatePlugin } from '@syndicate-lang/esbuild-plugin';

esbuild.build({
  ...
  plugins: [..., syndicatePlugin(), ...],
  ...
});

The syndicatePlugin function takes an optional options object. It may include properties:

• module, optional, drawn from "es6" (the default), "require", "global", or "none": controls how to get hold of an instance of the @syndicate-lang/core module. If es6, uses import; if require, uses require; if global, uses a global variable (useful for browser contexts); if none, does no imports, so some other provision will have to be made to ensure __SYNDICATE__ is bound to a module instance for the output code.

• runtime, optional string: defaults to "@syndicate-lang/core". For module of es6 or require, names the module to import/require, respectively; for module of global, an expression to yield a module instance.

  For example, in a browser, using a CDN to retrieve a dist/syndicate.js script from the @syndicate-lang/core package produces a Syndicate global variable, so you could set module to global and runtime to Syndicate or window.Syndicate etc.

• include, exclude: both optional arrays of strings. By default, include is ["**/*.{js,ts}"] and exclude is ["node_modules/**"]. Each time esbuild considers a module path, the Syndicate plugin first checks to see if it matches some glob in include (using outmatch). If not, the plugin delegates to esbuild's default handler. Otherwise, it checks to see if it matches some glob in exclude. If so, again it delegates to esbuild. Otherwise, it runs the Syndicate compiler on the module source code and hands that off to esbuild.
