Not working in SSR enviroments

[oskari]

In cookie.js#L10 a document -object is accessed but this might not be available in while in SSR, should probably be a check for if the document -object exists.

Facing this issue in Gatsby but I presume platforms like nextjs suffer the same?

@oskari
null check was added in the latest release
https://github.com/AddSearch/js-client-library/releases/tag/v0.8.6
Could you check again please?

[oskari]

I'm sorry, my initial description was written a bit too hastily. Null check isn't sufficient as the whole document object is not available.

ERROR  UNKNOWN

There was an error compiling the html.js component for the development server.
See our docs page on debugging HTML builds for help https://gatsby.dev/debug-html ReferenceError: document is not defined

  WebpackError: ReferenceError: document is not defined

  - cookie.js:12
    [www.mehilainen.fi]/[addsearch-js-client]/src/cookie.js:12:1

  - index.js:20
    [www.mehilainen.fi]/[addsearch-js-client]/src/index.js:20:1

I'd guess a better way around it would be typeof check, as seems to be the case in multiple js cookie libraries:

if (typeof document === 'undefined') {
    return
  }
