ReferenceError: window is not defined

[ochanje210]

From the latest version: 0.71.5, server-side rendering produces following issue

/var/app/current/node_modules/semantic-ui-react/dist/commonjs/behaviors/Visibility/Visibility.js:260
  context: window,

PRs are welcome. We already have isBrowser function to recognize if SSR is used.

Looks like the issue is coming from this commit: e350886

Perhaps we should wrap the defaultProps "context": window with an "isBrowser" check

ChrisNLott thanks for help!

I commented all changes from this commit (+two related comments in Sticky.js and Visibility.js) and my project start to work.

Hope it can help somebody)

Thank @ilinyevg, I try this and it work !

const hasWindow =
typeof window === 'object' && window !== null && window.self === window;

Visibility.defaultProps = {
  context: hasWindow ? window : {},
  continuous: false,
  once: true
};

I have wrote temporary script for fix this, perhaps for somebody will be useful

const fs = require( 'fs' );

const visibilityFile = 'node_modules/semantic-ui-react/dist/commonjs/behaviors/Visibility/Visibility.js';
const stickyFile = 'node_modules/semantic-ui-react/dist/commonjs/modules/Sticky/Sticky.js';

fs.readFile( visibilityFile, 'utf8', function ( err, data ) {
  if ( err ) {
    return console.error( err );
  }
  const result = data.replace( 'context: window', 'context: typeof window === \'object\' && window !== null && window.self === window ? window : {}' );

  fs.writeFile( visibilityFile, result, 'utf8', function ( err ) {
    if ( err ) return console.error( err );
  } );
} );

fs.readFile( stickyFile, 'utf8', function ( err, data ) {
  if ( err ) {
    return console.error( err );
  }
  const result = data.replace( 'scrollContext: window', 'scrollContext: typeof window === \'object\' && window !== null && window.self === window ? window : {}' );

  fs.writeFile( stickyFile, result, 'utf8', function ( err ) {
    if ( err ) return console.error( err );
  } );
} );

How's this going? Everything broke here :(

[ochanje210]

Falling back to 0.71.3 should be fine until this is fixed.

[WoLfulus]

I'm in a loop xD
Some features I use are broken in .3

I'll try the workarounds

I'm getting an error related to "window is not defined" when deploying to gatsby.
https://www.gatsbyjs.org/docs/debugging-html-builds/

I see multiple issues about this here and lots of discussion. Is there any consensus regarding a solution? if so should we add something to the docs?

• Server-side rendering with React.js Semantic-UI#4146
• ReferenceError: window is not defined #1987
• Modal relies on document as default renderNode, breaks SSR #712

[layershifter]

Just wait until #1990 will be merged and released in new version.

[prateekrastogi]

@layershifter Any eta on when project maintainers are planning to do so?

[levithomason]

I do my best to make a release every weekend. Sometimes I don't cause of life and free software :)

[ddenysov]

I still have this error in 0.72.0

scrollContext: typeof window === 'object' && window !== null && window.self === window ? window : {},

The code above fixed problem

[lookagit]

node V7.9.0
npm V4.2.0

[levithomason]

If users are having issues on the latest release, please open a new issue if there is not one already. The fields in the issue template are necessary for us to debug and ship fixes.

[curran]

Experiencing this error with SSR on version 0.75.1.

[moshest]

I add to webpack on the server side the following plugin:

  plugins: [
    // Define free variables
    // https://webpack.js.org/plugins/define-plugin/
    new webpack.DefinePlugin({
      window: undefined,
    }),
  ],

[levithomason]

We're happy to look at new issues posted against the latest version 0.77.0.
