GistKV

Use GitHub gists as simple key-value databases

What is this for?

Simple non-sensitive¹ datastore for scripts, crons, or CLI tools
MVP database for prototyping

Installation

gem install gistkv

Create a database

Use GistKV::Client.create_database to create a new GistKV database. The method requires passing a valid GitHub token with access to the gist scope.

require 'gistkv'

# returns id of created gist
GistKV::Client.create_database(ENV['GITHUB_TOKEN'])
# => f9ba626808266b93b7631aeb8321dbcf

Take note of the id returned from create_database when called, it should be saved for future use. This is the id of your database.

Use a database

Use GistKV::Client.new to create a GistKV client. This method requires passing the id of a GistKV gist and a valid GitHub token with access to the gist scope.

require 'gistkv'

g = GistKV::Client.new(ENV['GIST_ID'], ENV['GITHUB_TOKEN'])

# set a value
g.set("score", 10)

# get a value
g.get("score")
# => 10

# alias for .get
g["score"]
# => 10

# alias for .set
g["days"] = ["Friday", "Saturday", "Sunday"]

g.get("days")
# => ["Friday", "Saturday", "Sunday"]

# get list of keys
g.keys
# => ["score", "days"]

# update multiple keys at once
g.update(score: 11, days: ["Saturday"])

The above example code resulted in this gist.

It's also possible to create a read-only GistKV::Client by omitting the GitHub access token on creation. Please note this client will be subject to the GitHub API's public rate limits. See docs for more info.

How it works

GistKV creates a single __gistkv.json file in a gist.
On each .get or .set the gist's JSON is retrieved from the GitHub API, manipulated, and then written back to the gist.
- As a result, you may experience unexpected results if multiple client instances are reading/writing the same gist at once.

Footnotes

⚠️ Don't use GistKV to store sensitive data. Gists, even when set to secret, are not private. ⚠️ ↩
