This addon isn't as useful as it use to be. See the Impact section below.
ember-cli addon that mounts your broccoli tmp folder in RAM
for speedier builds.
Presently only supports OS X (Darwin) and Linux.
From your ember-cli project folder:
npm install ember-cli-ramdisk --save-dev
ember-cli uses Broccoli as a build tool, and Broccoli uses a tmp
folder in your project's directory for storing intermediate files during
the build process, which means they are getting stored on your hard
drive.
Most operating systems allow you to mount file systems into memory, which results in faster read/write operations with the obvious tradeoff being that if your computer restarts, you'll lose any data mounted on the ramdisk.
But for temporary folders that are often read/written into, you can get some performance gains by mounting them to a ramdisk, which is what this ember addon does.
At this point, if you're using an up-to-date version of ember-cli, you probably won't notice an improvement in build times from this addon.
Another use case for this addon is to prevent things like:
- SSD thrash,
- slow writes to magnetic drives
- fragmenting on Copy-On-Write filesystems like btrfs - see (http://blog.ieugen.ro/2015/03/my-experience-with-btrfs-on-debian.html)
This addon will:
- Mount a ramdisk at
- OS X -
/Volumes/EmberCliRamdisk - Linux -
/mnt/EmberCliRamdisk
- Replace your project's
tmpfolder with a symlink to/Volumes/EmberCliRamdisk/your-project-nameor/mnt/EmberCliRamdisk/your-project-name
Multiple projects can use this addon and share the same ramdisk.
The ramdisk does not automatically unmount after you kill broccoli, but can easily be unmounted from the side menu in Finder.
To unmount the ramdisk in linux you must run sudo umount /mnt/EmberCliRamdisk and sudo rm -R /mnt/EmberCliRamdisk/.
- Tests
- Support for OSs other than Mac (darwin) and Linux
- Replace execSync with something nicer (can't right now since
includedoesn't wait for any returned promises)
