snap-shot-store

Snapshots saved against an object

Install

Requires Node version 6 or above.

npm install --save snap-shot-store

Use

const { initStore } = require('snap-shot-store')
const snapshot = initStore()
// store / check values by name
snapshot({
  name: 'foo',
  value: 1
})
// can use list of names
snapshot({
  name: ['bar', 'baz'],
  value: 2
})
// get current store object
const store = snapshot()
// store is
// {foo: 1, bar: {baz: 2}}

There are aliases for remembering

snapshot({
  name: 'foo',
  value: 1
})
// is same as
snapshot({
  names: 'foo',
  what: 1
})

Can pass options to control store behavior. For example

const isCI = require('is-ci')
const { initStore } = require('snap-shot-store')
const snapshot = initStore()
snapshot({
  name: 'foo',
  value: 1,
  opts: {
    ci: isCI
  }
})
// will store value locally, but not on CI
// on CI an attempt to store / change value
// will raise an exception

A good set of environment variables to grab and pass as opts is

const opts = {
  show: Boolean(process.env.SNAPSHOT_SHOW),
  dryRun: Boolean(process.env.SNAPSHOT_DRY),
  update: Boolean(process.env.SNAPSHOT_UPDATE),
  ci: Boolean(process.env.CI)
}
