| * This file allows to perform a "fast" build of the RxPlayer's demo, by using | ||
| * esbuild. | ||

| * You can either run it directly as a script (run `node fast_demo_build.js -h` | ||
| * to see the different options) or by requiring it as a node module. | ||
| * If doing the latter you will obtain a function you will have to run with the | ||
| * right options. | ||
