MP4 file not loading on React / Rails app

问题

I'm getting this error. From what I can google, it needs to configure the webpack file but in this rails app it's a webpacker.yml file. CRA looks like it works fine when using the usual tag. Any help would be appreciated.

./app/javascript/components/User/cover.mp4 1:0 Module parse failed: Unexpected character '' (1:0) You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders (Source code omitted for this binary file)

回答1:

in config/webpacker.yml under static_assets_extensions add .mp4

static_assets_extensions
  - .mp4
  ...

create a new folder app/javascripts/static

then

const file = require('static/file.mp4')

render() {
  return (
    <div>
      <video controls>
        <source src={file} />
      </video>
  ...
