SDK Installation

The SDK can be installed with either npm, pnpm, bun or yarn package managers.

NPM

npm add @trytestify/sdk

PNPM

pnpm add @trytestify/sdk

Bun

bun add @trytestify/sdk

Yarn

yarn add @trytestify/sdk zod

# Note that Yarn does not install peer dependencies automatically. You will need
# to install zod as shown above.

Model Context Protocol (MCP) Server

This SDK is also an installable MCP server where the various SDK methods are exposed as tools that can be invoked by AI applications.

Node.js v20 or greater is required to run the MCP server from npm.

{
  "mcpServers": {
    "Testify": {
      "command": "npx",
      "args": [
        "-y", "--package", "@trytestify/sdk",
        "--",
        "mcp", "start"
      ]
    }
  }
}

{
  "mcpServers": {
    "Testify": {
      "command": "npx",
      "args": [
        "-y", "--package", "@trytestify/sdk",
        "--",
        "mcp", "start"
      ]
    }
  }
}

You can also run MCP servers as a standalone binary with no additional dependencies. You must pull these binaries from available Github releases:

curl -L -o mcp-server \
    https://github.com/{org}/{repo}/releases/download/{tag}/mcp-server-bun-darwin-arm64 && \
chmod +x mcp-server

If the repo is a private repo you must add your Github PAT to download a release -H "Authorization: Bearer {GITHUB_PAT}".

{
  "mcpServers": {
    "Todos": {
      "command": "./DOWNLOAD/PATH/mcp-server",
      "args": [
        "start"
      ]
    }
  }
}

For a full list of server arguments, run:

npx -y --package @trytestify/sdk -- mcp start --help

Requirements

For supported JavaScript runtimes, please consult RUNTIMES.md.

SDK Example Usage

Example

import { Testify } from "@trytestify/sdk";

const testify = new Testify();

async function run() {
  const result = await testify.testimonials.get({
    spaceId: "<id>",
  });

  console.log(result);
}

run();

Available Resources and Operations

Standalone functions

All the methods listed above are available as standalone functions. These functions are ideal for use in applications running in the browser, serverless runtimes or other environments where application bundle size is a primary concern. When using a bundler to build your application, all unused functionality will be either excluded from the final bundle or tree-shaken away.

To read more about standalone functions, check FUNCTIONS.md.

Retries

Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.

To change the default retry strategy for a single API call, simply provide a retryConfig object to the call:

import { Testify } from "@trytestify/sdk";

const testify = new Testify();

async function run() {
  const result = await testify.testimonials.get({
    spaceId: "<id>",
  }, {
    retries: {
      strategy: "backoff",
      backoff: {
        initialInterval: 1,
        maxInterval: 50,
        exponent: 1.1,
        maxElapsedTime: 100,
      },
      retryConnectionErrors: false,
    },
  });

  console.log(result);
}

run();

If you'd like to override the default retry strategy for all operations that support retries, you can provide a retryConfig at SDK initialization:

import { Testify } from "@trytestify/sdk";

const testify = new Testify({
  retryConfig: {
    strategy: "backoff",
    backoff: {
      initialInterval: 1,
      maxInterval: 50,
      exponent: 1.1,
      maxElapsedTime: 100,
    },
    retryConnectionErrors: false,
  },
});

async function run() {
  const result = await testify.testimonials.get({
    spaceId: "<id>",
  });

  console.log(result);
}

run();

Error Handling

TestifyError is the base class for all HTTP error responses. It has the following properties:

Example

import { Testify } from "@trytestify/sdk";
import * as errors from "@trytestify/sdk/models/errors";

const testify = new Testify();

async function run() {
  try {
    const result = await testify.testimonials.get({
      spaceId: "<id>",
    });

    console.log(result);
  } catch (error) {
    // The base class for HTTP error responses
    if (error instanceof errors.TestifyError) {
      console.log(error.message);
      console.log(error.statusCode);
      console.log(error.body);
      console.log(error.headers);

      // Depending on the method different errors may be thrown
      if (error instanceof errors.StandardError) {
        console.log(error.data$.message); // string
      }
    }
  }
}

run();

Error Classes

Primary errors:

• TestifyError: The base class for HTTP error responses.
  • StandardError: Generic error.

* Check the method documentation to see if the error is applicable.

Server Selection

Select Server by Index

You can override the default server globally by passing a server index to the serverIdx: number optional parameter when initializing the SDK client instance. The selected server will then be used as the default on the operations that use it. This table lists the indexes associated with the available servers:

Example

import { Testify } from "@trytestify/sdk";

const testify = new Testify({
  serverIdx: 1,
});

async function run() {
  const result = await testify.testimonials.get({
    spaceId: "<id>",
  });

  console.log(result);
}

run();

Override Server URL Per-Client

The default server can also be overridden globally by passing a URL to the serverURL: string optional parameter when initializing the SDK client instance. For example:

import { Testify } from "@trytestify/sdk";

const testify = new Testify({
  serverURL: "http://localhost:3000",
});

async function run() {
  const result = await testify.testimonials.get({
    spaceId: "<id>",
  });

  console.log(result);
}

run();

Custom HTTP Client

The TypeScript SDK makes API calls using an HTTPClient that wraps the native Fetch API. This client is a thin wrapper around fetch and provides the ability to attach hooks around the request lifecycle that can be used to modify the request or handle errors and response.

The HTTPClient constructor takes an optional fetcher argument that can be used to integrate a third-party HTTP client or when writing tests to mock out the HTTP client and feed in fixtures.

The following example shows how to use the "beforeRequest" hook to to add a custom header and a timeout to requests and how to use the "requestError" hook to log errors:

import { Testify } from "@trytestify/sdk";
import { HTTPClient } from "@trytestify/sdk/lib/http";

const httpClient = new HTTPClient({
  // fetcher takes a function that has the same signature as native `fetch`.
  fetcher: (request) => {
    return fetch(request);
  }
});

httpClient.addHook("beforeRequest", (request) => {
  const nextRequest = new Request(request, {
    signal: request.signal || AbortSignal.timeout(5000)
  });

  nextRequest.headers.set("x-custom-header", "custom value");

  return nextRequest;
});

httpClient.addHook("requestError", (error, request) => {
  console.group("Request Error");
  console.log("Reason:", `${error}`);
  console.log("Endpoint:", `${request.method} ${request.url}`);
  console.groupEnd();
});

const sdk = new Testify({ httpClient });

Debugging

You can setup your SDK to emit debug logs for SDK requests and responses.

You can pass a logger that matches console's interface as an SDK option.

import { Testify } from "@trytestify/sdk";

const sdk = new Testify({ debugLogger: console });

You can also enable a default debug logger by setting an environment variable TESTIFY_DEBUG to true.

Development

Maturity

This SDK is in beta, and there may be breaking changes between versions without a major version update. Therefore, we recommend pinning usage to a specific package version. This way, you can install the same version each time without breaking changes unless you are intentionally looking for the latest version.

Contributions

While we value open-source contributions to this SDK, this library is generated programmatically. Any manual changes added to internal files will be overwritten on the next generation. We look forward to hearing your feedback. Feel free to open a PR or an issue with a proof of concept and we'll do our best to include it in a future release.
