This library provides different node.js based authentication mechanisms for services in Azure. It also contains rich type definitions thereby providing good typescrit experience. All the authentication methods support callback as well as promise. IF they are called within an async method in your application then you can use the async/await pattern as well.

Example

username/password based login

import * as msRestNodeAuth from "ms-rest-nodeauth";

const username = process.env["AZURE_USERNAME"];
const password = process.env["AZURE_PASSWORD"];

msRestNodeAuth.loginWithUsernamePasswordWithAuthResponse(username, password).then((authres) => {
  console.dir(authres, { depth: null })
}).catch((err) => {
  console.log(err);
});

service-principal/secret based login

import * as msRestNodeAuth from "ms-rest-nodeauth";

const clientId = process.env["CLIENT_ID"];
const secret = process.env["APPLICATION_SECRET"];
const tenantId = process.env["DOMAIN"];

msRestNodeAuth.loginWithServicePrincipalSecretWithAuthResponse(clientId, secret, tenantId).then((authres) => {
  console.dir(authres, { depth: null })
}).catch((err) => {
  console.log(err);
});

interactive/device-code flow login

import * as msRestNodeAuth from "ms-rest-nodeauth";

msRestNodeAuth.interactiveLoginWithAuthResponse().then((authres) => {
  console.dir(authres, { depth: null })
}).catch((err) => {
  console.log(err);
});

service-principal authentication from auth file on disk

import * as msRestNodeAuth from "../lib/msRestNodeAuth";

const options: msRestNodeAuth.LoginWithAuthFileOptions = {
  filePath: "<file path to auth file>",
}
msRestNodeAuth.loginWithAuthFileWithAuthResponse(options).then((authRes) => {
  console.log(authRes);
  console.log(process.env["AZURE_SUBSCRIPTION_ID"]);
}).catch((err) => {
  console.log(err);
});

MSI(Managed Service Identity) based login from a virtual machine created in Azure.

import * as msRestNodeAuth from "../lib/msRestNodeAuth";

msRestNodeAuth.loginWithMSI("your-tenantId").then((msiTokenRes) => {
  console.log(msiTokenRes);
}).catch((err) => {
  console.log(err);
});
