e-Manifest NPM package

THIS REPO HAS BEEN MOVED

This project is now maintained in the USEPA/e-manifest repository.

Intro

The emanifest npm package is an API client library. It simplifies the task of using the RCRAInfo/e-Manifest web services by abstracting the authentication process, providing developer friendly API, and exporting TypeScript types. It's built on top of the Axios library, and can be used in both Node and browser runtime environments (EPA has discussed making some public API available that do not need authentication in the near future).

Installation

  $ npm install emanifest 
  or
  $ yarn add emanifest

Basic Usage

The primary export of the emanifest package is the newClient function. A constructor that accepts a configuration object and returns a new RcraClient instance.

import { AxiosResponse } from 'axios';
import { newClient, RCRAINFO_PREPROD, AuthResponse } from 'emanifest'

// The newClient accepts an instance of the RcraClientConfig which follows this interface
// interface RcraClientConfig {
// apiBaseURL?: RcrainfoEnv; // default: RCRAINFO_PREPROD
// apiID?: string;
// apiKey?: string;
// authAuth?: Boolean; // default: false
// }

const rcrainfo = newClient({ apiBaseURL: RCRAINFO_PREPROD, apiID: 'my_api_id', apiKey: 'my_api_key' })
const authResponse: AxiosResponse<AuthResponse> = await rcrainfo.authenticate()
console.log(authResponse.data)

Other Exports

The emanifest package also exports the RCRAINFO_PREPROD and RCRAINFO_PROD constants which can be used to set the apiBaseURL property of the RcraClientConfig object.

Types

The emanifest package exports a types/interfaces that can be used in statically typed projects. The types follow the OpenAPI schema definitions that can be found in the USEPA/e-manifest schema directory however, some names have been modified for clarity (for example RcraCode instead of simply Code).

Auto-Authentication

The emanifest package can be explicitly configured to automatically authenticate when needed.

import { AxiosResponse } from 'axios';
import { newClient, RCRAINFO_PREPROD, AuthResponse, RcraClientClass, RcraCode } from 'emanifest'

const rcrainfo = newClient({
  apiBaseURL: RCRAINFO_PREPROD,
  apiID: 'my_api_id',
  apiKey: 'my_api_key',
  autoAuth: true // Set the RcraClient to automatically authenticate as needed
})

// the authenticate method is NOT explicitly called
const resp: AxtiosResponse<RcraCode> = await rcrainfo.getStateWasteCodes('VA')

console.log(resp.data) // [ { code: 'BCRUSH', description: 'Bulb or Lamp Crusher' } ]

console.log(rcrainfo.isAuthenticated()) // true
