Beyond Basic APIs: Building Reliability with Functions.do

Building reliable and predictable applications is a cornerstone of successful software development. While traditional APIs provide a way to interact with services, they often introduce a layer of uncertainty, particularly when dealing with dynamically typed languages or external dependencies. This is where Functions.do steps in, offering a different approach to function execution that prioritizes typesafety and reliability.

The Pain of Runtime Errors

We've all been there. You deploy an update, confident that everything is working, only to receive error reports pointing to unexpected data types or missing properties at runtime. These runtime errors can be costly, leading to downtime, frustrated users, and significant debugging efforts. Traditional API interactions, especially with loosely defined schemas or lack of rigorous validation, are a common source of such issues.

Introducing Functions.do: Typesafe Function Execution

Functions.do is a Function Execution Platform designed to eliminate these pain points by focusing on compile-time type checking and robust validation. Instead of relying solely on runtime checks, Functions.do leverages the power of strong typing to catch potential errors before your code even runs. This proactive approach significantly reduces the likelihood of encountering unexpected issues in production.

Think of it as Generative AI Functions That Just Work. You define the expected input and output types for your functions, and Functions.do ensures that these contracts are honored. This makes your applications more predictable, easier to maintain, and ultimately, more reliable.

How Functions.do Achieves Reliability

Functions.do achieves this level of reliability through several key features:

• Compile-time Type Checking: By defining clear types for your function inputs and outputs, Functions.do allows tools and compilers to verify that your code adheres to these types before execution. This catches a significant class of errors early in the development cycle.
• Built-in Validation: Beyond basic type checking, Functions.do provides mechanisms for defining more complex validation rules. This ensures that even if the data type is correct, the data itself meets your specific requirements.
• Strongly-Typed AI Interactions: Functions.do particularly shines when working with Generative AI. The platform allows you to define structured types for your AI prompts and responses, ensuring that you receive the data you expect in a predictable format. No more parsing ambiguous strings or guessing at the structure of AI output.

Example: Working with Typesafe AI

Let's look at the provided code example:

import { AI } from 'functions.do'

const ai = AI({
  leanCanvas: {
    productName: 'name of the product or service',
    problem: ['top 3 problems the product solves'],
    solution: ['top 3 solutions the product offers'],
    uniqueValueProposition: 'clear message that states the benefit of your product',
    unfairAdvantage: 'something that cannot be easily copied or bought',
    customerSegments: ['list of target customer segments'],
    keyMetrics: ['list of key numbers that tell you how your business is doing'],
    channels: ['path to customers'],
    costStructure: ['list of operational costs'],
    revenueStreams: ['list of revenue sources'],
    recommendations: ['list of recommendations based on the analysis'],
  },
})

In this example, we are using AI from functions.do and defining a structured type for the leanCanvas output. This tells Functions.do exactly what kind of data we expect from the AI function. If the AI model returns something that doesn't conform to this structure (e.g., productName is an array instead of a string), Functions.do will flag this issue, preventing potential runtime errors down the line. This makes working with AI without complexity.

Beyond Reliability: Business-as-Code and Services-as-Software

Functions.do isn't just about preventing errors; it's about building reliable applications efficiently. The typesafe nature of the platform makes your code more readable, maintainable, and easier to refactor. It promotes a Business-as-Code and Services-as-Software paradigm, where your business logic and services are clearly defined and executable through reliable functions.
