STDB-VM

SpacetimeDB Version Manager (Windows only atm)
( This repo has no official association with SpacetimeDB )

This tool is useful when:

1. Wanting to change STDB versions with ease (run old projects, git-bisect, upgrading etc.)
2. Working on two STDB projects at the same time and switching relatively frequently.
3. Frequently switching between two branches on different versions.
4. Testing how old and new systems interact with each other:
   • e.g. test how old client generated bindings and UI interact with new DB updates/modules. Useful for live module updates, slow roll-outs, zero-downtime/non-forced/manual update systems, etc.
5. Offline version switching.
6. Loading the earliest and latest of versions.

Getting Started

Using:

npm i -g stdb-vm
stdb-vm <cmd> <args...> <options...>
# alias
stvm <cmd> <args...> <options...>

Set default version from release listings with --remote flag:

stvm set -r
# apply given env patch

Use --direct flag to point to different local versions simultaneously:

# Terminal 1
stvm set version-1 -d # apply given env patch
stvm start -l="host1" # please ensure host exists

# Terminal 2
stvm set version-2 -d # apply given env patch
stvm start -l="host2" # please ensure host exists

# later - return to default instance
stvm use-default 

Developing:

# clone, then:
npm i
npm start -- <cmd> <args...> <options...>

# Generate cli docs
npm run docs

# build
npm run build
npm run built:Test -- <cmd> <args...> <options...>

# test globally (make sure to build first!)
npm install -g .
npm uninstall -g stdb-vm

Todo:

• Selection lists
• Publish: Build, npm dist, and make globally accessible

• Refactor (cmd route like directories, group vue and commander cmds, components dir)
• Doc generations (determine if cmd or import, iterate over help)
• Add support for other OS's
• Pure semver support so you don't have to be picky with tag names
  • https://docs.npmjs.com/cli/v6/using-npm/semver
• Use loading bar component for downloads
• rmdb cmd to remove db's in .spacetime/versions

I wonder if perhaps I should only allow -d to be applied via env patch so people don't wind up stuck on a direct version without realizing.
