Handle CORS Client-side

Cross-origin resource sharing (CORS) is a mechanism that allows restricted resources (e.g. fonts) on a web page to be requested from another domain outside the domain from which the first resource was served. This is set on the server-side and there is nothing you can do from the client-side to change that setting, that is up to the server/API. There are some ways to get around it tho.

Sources : MDN - HTTP Access Control | Wiki - CORS

CORS is set server-side by supplying each request with additional headers which allow requests to be requested outside of the own domain, for example to your localhost. This is primarily set by the header:

Access-Control-Allow-Origin

This guide is based on the hibernate article from the Arch wiki.

edit /etc/default/grub and add resume as well as resume_offset kernel parameters
- resume=UUID=abcd-efgh contains the UUID of the partition on which the swapfile resides. In most cases the swapfile resides in root, to identify the root parition's UUID run blkid or lsblk -O.
- resume_offset=1234 is the offset of the swapfile from the partition start. The offset is the first entry in the physical_offset column of the output of filefrag -v /swapfile.
- update grub: grub-mkconfig -o /boot/grub/grub.cfg
- example: GRUB_CMDLINE_LINUX_DEFAULT="resume=UUID=75972c96-f909-4419-aba4-80c1b74bd605 resume_offset=1492992"
add the resume module hook to /etc/mkinitcpio.conf:
- HOOKS="base udev resume autodetect ...
