@warrantdev/warrant-js

Use Warrant as an ES module.

Installation

Use npm to install the Warrant module:

npm install @warrantdev/warrant-js

Usage

Import the Warrant client and pass a valid Config object to the constructor to get started:

import Warrant from "@warrantdev/warrant-js";

// A valid session token is required to initialize the Client
const warrant = new Warrant({
  clientKey: "client_test_f5dsKVeYnVSLHGje44zAygqgqXiLJBICbFzCiAg1E=",
  sessionToken: "sess_test_f9asdfASD90mkj2jXZIaeoqbIUAIjsJAHSAnsndW=",
});

check

This function returns a Promise that resolves with true if the user for the current session token has the specified warrant and false otherwise.

import Warrant from "@warrantdev/warrant-js";

// A valid session token is required to initialize the Client
const warrant = new Warrant({
  clientKey: "client_test_f5dsKVeYnVSLHGje44zAygqgqXiLJBICbFzCiAg1E=",
  sessionToken: "sess_test_f9asdfASD90mkj2jXZIaeoqbIUAIjsJAHSAnsndW=",
});

//
// Example Scenario:
// An e-commerce website where Store Owners can edit their own Store's info
//
warrant.check({ object: myReport, relation: "editor" }).then((isAuthorized) => {
  if (isAuthorized) {
    // Carry out logic to allow user to edit a Store
  }
});

Or using async/await:

import Warrant from "@warrantdev/warrant-js";

// A valid session token is required to initialize the Client
const warrant = new Warrant({
  clientKey: "client_test_f5dsKVeYnVSLHGje44zAygqgqXiLJBICbFzCiAg1E=",
  sessionToken: "sess_test_f9asdfASD90mkj2jXZIaeoqbIUAIjsJAHSAnsndW=",
});

//
// Example Scenario:
// An e-commerce website where Store Owners can edit their own Store's info
//
const isAuthorized = await warrant.check({
  object: myReport,
  relation: "editor",
});
if (isAuthorized) {
  // Carry out logic to allow user to edit a Store
}

checkMany

This function returns a Promise that resolves with true if the user for the current session token has allOf or anyOf (depending on the passed in op) the specified warrants and false otherwise.

CheckOp.AnyOf specifies that the access check request will be authorized if any of the warrants are matched and will not be authorized otherwise.

CheckOp.AllOf specifies that the access check request will be authorized if all of the warrants are matched and will not be authorized otherwise.

import Warrant, { CheckOp } from "@warrantdev/warrant-js";

// A valid session token is required to initialize the Client
const warrant = new Warrant({
  clientKey: "client_test_f5dsKVeYnVSLHGje44zAygqgqXiLJBICbFzCiAg1E=",
  sessionToken: "sess_test_f9asdfASD90mkj2jXZIaeoqbIUAIjsJAHSAnsndW=",
});

warrant
  .checkMany({
    op: CheckOp.AllOf,
    warrants: [
      {
        object: tenantA,
        relation: "member",
      },
      {
        object: reportA,
        relation: "editor",
      },
    ],
  })
  .then((isAuthorized) => {
    if (isAuthorized) {
      // Carry out logic if user is member of tenantA AND editor of reportA
    }
  });

Or using async/await:

import Warrant from "@warrantdev/warrant-js";

// A valid session token is required to initialize the Client
const warrant = new Warrant({
  clientKey: "client_test_f5dsKVeYnVSLHGje44zAygqgqXiLJBICbFzCiAg1E=",
  sessionToken: "sess_test_f9asdfASD90mkj2jXZIaeoqbIUAIjsJAHSAnsndW=",
});

const isAuthorized = await warrant.checkMany({
  op: CheckOp.AllOf,
  warrants: [
    {
      object: tenantA,
      relation: "member",
    },
    {
      object: reportA,
      relation: "editor",
    },
  ],
});
if (isAuthorized) {
  // Carry out logic if user is member of tenantA AND editor of reportA
}

This function returns a Promise that resolves with true if the user for the current session token has the specified permission and false otherwise.

import Warrant from "@warrantdev/warrant-js";

// A valid session token is required to initialize the Client
const warrant = new Warrant({

  sessionToken: "sess_test_f9asdfASD90mkj2jXZIaeoqbIUAIjsJAHSAnsndW=",
});

warrant.hasPermission({ permissionId: "view-items" }).then((canViewItems) => {
  if (canViewItems) {
    // Carry out logic if user has permission view-items
  }
});

Or using async/await:

import Warrant from "@warrantdev/warrant-js";

// A valid session token is required to initialize the Client
const warrant = new Warrant({
  clientKey: "client_test_f5dsKVeYnVSLHGje44zAygqgqXiLJBICbFzCiAg1E=",
  sessionToken: "sess_test_f9asdfASD90mkj2jXZIaeoqbIUAIjsJAHSAnsndW=",
});

const canViewItems = await warrant.hasPermission({
  permissionId: "view-items",
});
if (canViewItems) {
  // Carry out logic if user has permission view-items
}

hasFeature

This function returns a Promise that resolves with true if the user for the current session token has the specified feature and false otherwise.

  sessionToken: "sess_test_f9asdfASD90mkj2jXZIaeoqbIUAIjsJAHSAnsndW=",
});

warrant.hasFeature({ featureId: "save-items" }).then((canSaveItems) => {
  if (canSaveItems) {
    // Carry out logic if user has feature save-items
  }
});

Or using async/await:

import Warrant from "@warrantdev/warrant-js";

// A valid session token is required to initialize the Client
const warrant = new Warrant({
  clientKey: "client_test_f5dsKVeYnVSLHGje44zAygqgqXiLJBICbFzCiAg1E=",
  sessionToken: "sess_test_f9asdfASD90mkj2jXZIaeoqbIUAIjsJAHSAnsndW=",
});

const canSaveItems = await warrant.hasFeature({ featureId: "save-items" });
if (canSaveItems) {
  // Carry out logic if user has feature save-items
}

We’ve used a random Client Key in these code examples. Replace it with your actual publishable Client Key to test this code through your own Warrant account.

TypeScript support

This package includes TypeScript declarations for Warrant.

Note that we may release new minor and patch versions of @warrantdev/warrant-js with small but backwards-incompatible fixes to the type declarations. These changes will not affect Warrant itself.
