Signal, a feature flag library

How it works:

Signal is configured with 2 required options and 1 optional option. The required options are user and flags. A user object represents the object that will be used to determine certain fields that are used.

Flag data shape:

required fields:

type: Valid options are: percentage, list, switch, all, any

percentage

list

switch

a simple boolean flag

all

any

key: key used in lookup object

data: data used by each flag type. percentage is the percent value. for list it's a list of values. For switch it's true or false. For all and any it's a list of other flag names

active: true or false, determines if the flag is stored in the lookup object

property: the identifier used to lookup data from the user object. Varies in usage between flags.

Example Usage

t aws = require('aws-sdk');
t db = new AWS.DynamoDB.DocumentClient();
t params = {
bleName : 'Table',
lterExpression : 'active = :active',
pressionAttributeValues : {':active' : true}


can(params).promise()
hen(response => response.Items)
hen(flags => {
return signal.config({user, flags})
;



signal.isEnabled('waypoint')) {
 show waypoint stuff
