Usage

import experiment from '@felipelealdefaria/experiments-service'

1) Initialize:

This is required before any other methods can be called.

await experiment.init(params: InitParams): Promise<InitResponse>

InitParams:
- baseUrl: string
- timeout?: number (default: 8000)

InitResponse:
- session: unknown
- error?: boolean
- success?: boolean
- message?: string

2) Experiment Participate:

To start an experiment (test a/b).

await experiment.participate(params: ParticipateParams) => Promise<ParticipateResponse>

ParticipateParams
- session: unknown
- traffic?: number (default: 1) // means 50% for each variable
- variationsName: string[]
- experimentName: string

ParticipateResponse
- alternativeName?: string | null
- experimentName?: string | null
- error?: boolean
- success?: boolean
- message?: string

3) Experiment Convert:

To convert an experiment KPI.

await convert(params: ConvertParams) => Promise<ConvertResponse>

ConvertParams
- kpi?: string
- session: unknown
- experimentName: string

ConvertResponse
- kpi?: string
- experimentName?: string
- alternativeName?: string
- error?: boolean
- success?: boolean
- message?: string

4) A/B Test with React.Js:

return (
  <>
    { res?.alternativeName === 'variant_option'} ? <ComponentA /> : <ComponentB /> }
  </>
)

OBS To force the variation, insert in your browser cookies:

key: force-${experimentName}
value: ${variation_option}

Possible error for those using webpack

The dependency of the project, sixpack-client has incompatibility with some versions of the webpack. The common error in this case may be linked to not being able to resolve the http and buffer dependencies.

To fix it, in your webpack.config.js file:

resolve: {
    fallback: {
      http: require.resolve('stream-http'),
      buffer: require.resolve('buffer/')
    }
}

Service's Architecture

Service created using the principles of Clean Architecture with the intention of facilitating maintenance and a possible exchange of lib used to perform A/B tests.
