gatsby build fails with FATAL ERROR exit code 134: JavaScript heap out of memory

[melo0187]

Hey there, thanks for this starter!
It looks interesting and I appreciate how you make everything editable through netlify cms.

I wanted to give it a try, but sadly the develop build fails.
Running gatsby build fails with exit code 134 and this output:

[...] // all good up to this point

It always fails at Building production JavaScript and CSS bundles.
This is true for two local attempts on different machines and for netlify, too.
It is 100% reproducible meaning I did not manage to create a production build from your starter yet. I did not start making any modifications to it.

So is it just me or is this failing for everyone?
I did not manage to find anything that acutally indicates the source of the problem, but I'm happy to help looking further into it.

See gatsbyjs/gatsby#15190 (comment)

[melo0187]

@edemirbag thank you for pointing out that option. It looks like --max_old_space_size is a V8 option available for node. Do you know what it actually does?

I actually preferred following another path after reading through gatsbyjs/gatsby#15256 and upgraded some dependencies in the starter:

-    "gatsby": "^2.0.98",
+    "gatsby": "^2.14.0",
-    "gatsby-plugin-netlify-cms": "^3.0.10",
+    "gatsby-plugin-netlify-cms": "^4.1.11",
-    "netlify-cms": "^2.3.3",
+    "netlify-cms": "^2.9.7",

This way gatsby build is succeeding both locally and on netlify without the need to set NODE_OPRTIONS env var.
In the process of this I noticed that netlify-cms is deprecated anyway, so I'm considering to swap that one out for netlify-cms-app.

@v4iv maybe you want to consider to update the 3 dependencies mentioned above to allow gatsby build to work out of the box?

hey @melo0187 thanks for notifying, will make the required updates, just one question:

In the process of this I noticed that netlify-cms is deprecated anyway, so I'm considering to swap that one out for netlify-cms-app.

what do you mean by 'netlify-cms is deprecated'?

[melo0187]

@v4iv When performing npm install I noticed the command output saying, that netlify-cms is deprecated and that it can be replaced with netlify-cms-app. The strange thing about it is that the official netlifycsm documentation still points to the netlify-cms package and not to netlify-cms-app, see here

Anyway, I quickly tried to "migrate" from netlify-cms to netlify-cms-app, with the only required code change being the line CMS.init added to cms.js before any other call to CMS.
It all builds and can be deployed to netlify, where I managed to test the CMS and did not notice any errors.

[v4iv]

@melo0187 when I tried updating I didn't get any such output, and given that the documentation still states 'netlify-cms', we'll be sticking to that for now.

[melo0187]

@v4iv I need to partially correct myself.
The deprecation warning did not show up in the output of npm install.

But it did show up in the gatsby build output. Furthermore this only happend after I fixed the build by updating the dependencies gatsby, gatsby-plugin-netlify-cms and netlify-cms to the versions I stated in the diff above.
I found the output in my netlify deployment history, too. See for yourself:

1:42:04 PM: Executing user command: gatsby build
1:42:08 PM: success open and validate gatsby-configs — 0.229
1:42:10 PM: success load plugins — 2.186
1:42:10 PM: warning The netlify-cms package is deprecated, please install netlify-cms-app instead. You can do this by running "npm install netlify-cms-app"
1:42:10 PM: success onPreInit — 0.049

@melo0187 thanks, I did check and I found it as well, thank you for notifying
