@salespark/mailerlite-api

MailerLite API v2 Node.js SDK. It is mostly a thin wrapper on axios that provides authentication, response/request camelCase transformations, Typescript type definitions and some handy shorthand methods.

📦 Installation

yarn add @salespark/mailerlite-api

# or

npm install @salespark/mailerlite-api

🚀 Usage

In node:

const MailerLite = require('@salespark/mailerlite-api');

const mailerLite = MailerLite('YOUR_API_KEY');

// with Promises
mailerLite.getAccount().then((account) => {
  // ...
});

// with async await
async function getAccountEmail() {
  const { email } = await mailerLite.getAccount();
  return email;
}

It is important to note that the request is resolved to response body - it does not return the full axios response object.

⚙️ Options

axiosOptions: object - additional axios config. This config does not overwrite the explicit baseURL and headers options below.

baseURL: string - API endpoint. Defaults to https://api.mailerlite.com/api/v2/. Timezones endpoint has a different hardcoded baseURL.

headers: object - additional request headers. Library already includes all the necessary headers to perform requests. But these can be overwritten with this option. Defaults to {}.

useCaseConverter: boolean - should the library convert all query params, request body and response body to camelCase. Defaults to true.
