There's so so much goodness available from tapping vm's as such, as virtual machines that we might do cool checkpoint/restore off on. Java has had some similar abilities to rebuild the pre-compiled stdlib with whatever else you want already included. So, each Java instance both boots faster & has less overhead. Forgetting the name though! Node has options too! https://nodejs.org/api/cli.html#--build-snapshot https://nodejs.org/api/cli.html#--build-snapshot

Problem with Node is that the snapshot functionality has several severe limitations. Copy pasted from NodeJS docs: --- Currently the support for run-time snapshot is experimental in that: 1. User-land modules are not yet supported in the snapshot, so only one single file can be snapshotted. Users can bundle their applications into a single script with their bundler of choice before building a snapshot, however. 2. Only a subset of the built-in modules work in the snapshot, though the Node.js core test suite checks that a few fairly complex applications can be snapshotted. Support for more modules are being added. If any crashes or buggy behaviors occur when building a snapshot, please file a report in the Node.js issue tracker and link to it in the tracking issue for user-land snapshots. --- (1) is fine as you can use a bundler to work around it. (2) can't, as far as I know, be worked around.
