2. Composio: Ultimate platform for AI automation
We are witnessing unprecedented growth in the AI landscape. For me, it resembles the 1990s internet boom. Big companies like Google, OpenAI, Microsoft, etc., are betting billions on an AI future.
Composio is the only tool you need to build complex AI automation software. Composio allows AI models to access 3rd party tools and applications to automate interaction with them.
🎯 For instance, you can connect GitHub with the GPT model via Composio and automate reviewing PRs, resolving issues, writing test cases, etc.
It houses over 90 tools and integrations, such as GitHub, Jira, Slack, and Gmail, to automate complex real-world workflows.
Moreover, you can even integrate your applications, enabling AI to take actions like sending emails, simulating clicks, placing orders, and much more just by adding the OpenAPI spec of your apps to Composio.
Some of the critical highlights of Composio
- SOC-II-approved and Role-based authentication control for enterprise users.
- A single-plane monitoring dashboard is used for all the integrations.
- Framework agnostic: use any AI framework like LangChain or LlamaIndex or build it raw.
- It handles complex user authentication and authorization for all your users, including OAuth, JWT, API Key, and basic authentication.
- Native support for Python and Javascript.
Here is how you can start with Composio with npm,
npm install composio-core
Define a method to let the user connect their GitHub account.
import { OpenAI } from "openai";
import { OpenAIToolSet } from "composio-core";
const toolset = new OpenAIToolSet({
apiKey: process.env.COMPOSIO_API_KEY,
});
async function setupUserConnectionIfNotExists(entityId) {
const entity = await toolset.client.getEntity(entityId);
const connection = await entity.getConnection('github');
if (!connection) {
// If this entity/user hasn't already connected, the account
const connection = await entity.initiateConnection(appName);
console.log("Log in via: ", connection.redirectUrl);
return connection.waitUntilActive(60);
}
return connection;
}
Add the required tools to the OpenAI SDK and pass the entity name on to the executeAgent function.
async function executeAgent(entityName) {
const entity = await toolset.client.getEntity(entityName)
await setupUserConnectionIfNotExists(entity.id);
const tools = await toolset.get_actions({ actions: ["github_activity_star_repo_for_authenticated_user"] }, entity.id);
const instruction = "Star a repo ComposioHQ/composio on GitHub"
const client = new OpenAI({ apiKey: process.env.OPEN_AI_API_KEY })
const response = await client.chat.completions.create({
model: "gpt-4-turbo",
messages: [{
role: "user",
content: instruction,
}],
tools: tools,
tool_choice: "auto",
})
console.log(response.choices[0].message.tool_calls);
await toolset.handle_tool_call(response, entity.id);
}
executeGithubAgent("joey")
Execute the code and let the agent do the work for you.

4. AssemblyScript - Typescript-like language for WebAssembly
There is a growing trend in building applications for web assembly or WASM to offer a native experience on the web, especially for compute-heavy tasks like animation, games, editors, etc.
If you want to build similar applications, AssemblyScript can be a great choice.
It is a typescript-like language that compiles to WebAssembly using **Binaryen** instead of JS.
Its close association with JS/TS syntax makes it ideal for developers to build near-native web apps without learning low-level languages.
The key features of AssemblyScript include
- Language familiarity for most developers.
- Near-native web performance.
- Fast and lightweight.
It is easy to get started with the Assembly script.
npm install --save-dev assemblyscript
Once installed, the compiler provides a handy scaffolding utility to quickly set up a new project here in the current directory:
npx asinit .
The asinit command automatically creates the recommended directory structure and configuration files:
The example in assembly/index.ts can now be compiled to WebAssembly by invoking the build command:
npm run asbuild
Doing so will emit the compiled binaries, bindings and definition files to the build/ directory.
The generated test case in tests/index.js can be executed with:
npm test
Once built, the directory contains all the bits to use the module like any other modern Node.js ESM module:
import * as myModule from "myModule";
The generated index.html shows how the module can be used on the Web. A web server serving the module directory, defaulting to display index.html, can be started with:
npm start
For more information on AssemblyScript, refer to their repository.

13. Zod - TypeScript-first schema validation with static type inference
Zod is a Typescript=first schema declaration and validation library. It allows you to define schemas for data structures and validate them with TypeScript type inference, ensuring that your data conforms to specific shapes and rules.
Typescript is only type-safe at compile time; Zod validates the data at runtime, ensuring that invalid data doesn’t slip through.
Key features
- Zero dependencies
- Works in Node.js and all modern browsers
- Tiny: 8kb minified + zipped
- Immutable: methods (e.g.
.optional()) return a new instance - Concise, chainable interface
- Functional approach: parse, don't validate
- It works with plain JavaScript, too! You don't need to use TypeScript.
Get started by installing Zod.
npm install zod
Creating a simple string schema
import { z } from "zod";
// creating a schema for strings
const mySchema = z.string();
// parsing
mySchema.parse("tuna"); // => "tuna"
mySchema.parse(12); // => throws ZodError
// "safe" parsing (doesn't throw error if validation fails)
mySchema.safeParse("tuna"); // => { success: true; data: "tuna" }
mySchema.safeParse(12); // => { success: false; error: ZodError }
Creating an object schema
import { z } from "zod";
const User = z.object({
username: z.string(),
});
User.parse({ username: "Ludwig" });
// extract the inferred type
type User = z.infer<typeof User>;
// { username: string }
