A tiny zero-dependency Truestamp SDK library written in Typescript for Deno, Node.js, and modern browsers.

Usage of this library requires an active Truestamp account, and an API key in order to communicate with the API back end.

• Small library size
• Zero dependencies
• Built with Typescript
• Promise based API (async/await)
• Supports Deno (ESM), Node.js (CommonJS), and modern browsers (ESM, UMD)
• esm.sh CDN support
• SkyPack CDN support
• JSDELIVR CDN support
• UNPKG CDN support

The TypeScript API documentation for this project is generated and published upon each new release.

Documentation about the Truestamp server-side REST API can be found at https://docs.truestamp.com/.

How to install and import the Truestamp code using different runtime environments.

npm install @truestamp/truestamp-js --save

const Truestamp = require("@truestamp/truestamp-js")
...

// Load module from esm.sh CDN, pinned to a specific version.
import Truestamp from "https://esm.sh/@truestamp/[email protected]"
...

<!-- load from JSDELIVR CDN latest (using latest not recommended for production use, pin a version) -->
<!-- See : https://www.jsdelivr.com/package/npm/@truestamp/truestamp-js -->
<script src="https://cdn.jsdelivr.net/npm/@truestamp/truestamp-js@latest/dist/truestamp.umd.min.js"></script>

<!-- load from UNPKG CDN latest (using latest not recommended for production use, pin a version) -->
<!-- See : https://unpkg.com/browse/@truestamp/truestamp-js/ -->
<script src="https://unpkg.com/@truestamp/truestamp-js"></script>

Each function provided on the Truestamp class returns a result in the form of an object with two properties success and data.

• success is a boolean that indicates if the request completed successfully or not.
• data is an Object representing the response from the API and can represent a valid response or an error response.

After each call to a Truestamp class function you should test whether it was successful and respond appropriately in your code.

You should not expect this library to throw exceptions. If it does please file a bug.

// See installation section for your runtime environment.
import Truestamp from "@truestamp/truestamp-js"

// A TRUESTAMP_API_KEY environment variable can also be set in your
// environment in place of providing the `apiKey` value as an argument.
const truestamp = new Truestamp({ apiKey: "%yourApiKey%" })

const myHash =
  "e728e4adeb8c0606fce4686552338622efeb8c63b53d072a323a4914d1aa5c07"

// Create new Item
const { success, data } = await truestamp.createItem(
  {
    itemData: [
      {
        hash: myHash,
        hashType: "sha-256",
      },
    ],
  },
  { skipCF: false, skipOE: false }
)

if (!success) {
  console.log("API call failed")
  console.log(data) // Contains Error JSON
  process.exit(1)
}

// Success! Contains good response JSON
console.log("createItem", data)

There are working code examples for Deno, Node.js, and the Web in the /examples directory. Take a look at the examples/README.md for usage instructions.

We'd love you to join our network of contributors. Please read CONTRIBUTING.md for help getting started.

The tests run actual requests against the public API. You'll need to export the following environment variables locally.

export TRUESTAMP_ENV=development
export TRUESTAMP_API_KEY=...

• Commit changes, and merge any pull requests to the main branch
• Bump the version field in package.json
