Hi.
I'm porting my blog to this theme.
There are around 130 articles, each with one cover image (well, actually there are some more, but I temporarily deleted them to try to fix this issue).
When compiling it, I used to see an error about heap allocation.
To solve it locally I had to increase the memory limit of the build process, updating the build command in the package.json file:
"build": "cross-env NODE_OPTIONS=--max-old-space-size=16384 gatsby build --prefix-paths",
"develop": "cross-env NODE_OPTIONS=--max-old-space-size=16384 gatsby develop",
