GopherJS Playground: Snippets are failing to load/save due to host name change.

[dmitshur]

Snippets are currently not working. It seems that the hostname was previously http://gopherjs.org, but now it redirects to http://www.gopherjs.org (/cc @neelance, @ajhager), which results in the XHR failing:

XMLHttpRequest cannot load http://snippets.gotools.org/p/D9L6MbPfE4. The 'Access-Control-Allow-Origin' header has a value 'http://gopherjs.org' that is not equal to the supplied origin. Origin 'http://www.gopherjs.org' is therefore not allowed access.

Fixed with gopherjs/snippet-store@06a3903 and deploying the new version of snippet-store that uses the new http://www.gopherjs.org value for Access-Control-Allow-Origin header.

Thx for the fix. What about putting the snippet store to a proper subdomain?

What about putting the snippet store to a proper subdomain?

What do you have in mind?

[neelance]

Just snippets.gopherjs.org instead of snippets.gotools.org.

[dmitshur]

That is completely okay with me. It requires 3 steps:

• you map that subdomain to the same IP as the current one,
• I'll add a port 80 redirect for that subdomain host to snippet-server.
• change playground source to use new name and redeploy.

[neelance]

DNS record created.

[dmitshur]

Port 80 redirect rule added, http://snippets.gopherjs.org/p/D9L6MbPfE4 now works.

The last remaining step is to change playground.go source to use the new host, rebuild it, and deploy (by merging the PR).

[dmitshur]

Okay, I've started the last step in PR #21, but neelance/go-angularjs#7 needs to be merged first and then the playground needs to be rebuilt (run update.sh) before that PR can be merged.

[dmitshur]

Last step done in #21, and with that the transition to snippets.gopherjs.org instead of snippets.gotools.org is complete.
