Usage with Internet Explorer 11

IE11 is supported in readonly mode, but depending on your runtime (webpack, nextjs, etc.), you might need additional configuration.

transpiling additional node_modules

react-page uses slate, which is currently not shipped in legacy ecmascript anymore, so you need to transpile it first. There are other modules as well that needs transpiling:

• slate
• slate-hyperscript
• slate-react
• uniforms
• uniforms-material
• uniforms-bridge-simple-schema-2

in nextjs you can do it with:

yarn add next-transpile-modules / npm install --save next-transpile-modules

and then in your next.config.js:

const withTM = require('next-transpile-modules')([
  'slate',
  'slate-hyperscript',
  'slate-react',
  'uniforms',
  'uniforms-material',
  'uniforms-bridge-simple-schema-2',
]);

module.exports = withTM({
  // rest of your config
});

Polyfills

you might also need some polyfils, the easiest way is to use this:

<script src="https://polyfill.io/v3/polyfill.min.js?features=String.prototype.repeat%2CString.prototype.startsWith%2CString.prototype.endsWith%2CSet%2CMap%2CURLSearchParams%2CArray.from" />
