safe-try-with-ai

A lightweight JavaScript utility for clean error handling with optional AI-style runtime suggestions, without repetitive try/catch blocks.

---

Installation

npm install safe-try-with-ai

---

Usage

Synchronous example

const { safeTry } = require("safe-try-with-ai");

const [err, result] = safeTry(() => JSON.parse('{"x":1}'));

if (err) {
  console.error(err);
} else {
  console.log(result); // { x: 1 }
}

---

Asynchronous example

const { safeTryAsync } = require("safe-try-with-ai");

const [err, data] = await safeTryAsync(async () => {
  return await fetchData();
});

if (err) {
  console.error(err);
}

---

Optional AI Runtime Suggestions

Enable AI-style runtime suggestions by passing { analyze: true } as the second argument.

const { safeTry } = require("safe-try-with-ai");

const [err] = safeTry(() => JSON.parse("invalid"), { analyze: true });

if (err) {
  console.error("Error:", err.message);
  console.log("Suggestion:", err.suggestion);
  console.log("Fix:", err.fix);
}

AI-style suggestions are rule-based and local. No real AI model, no network calls, no data collection.

---

Default Fallback Value

Use safeTryDefault to return a fallback value when an error occurs.

const { safeTryDefault } = require("safe-try-with-ai");

const result = safeTryDefault(
  () => JSON.parse("invalid"),
  {},
  { analyze: true }
);

console.log(result); // {}

---

Safe JSON Parsing

const { safeTryJson } = require("safe-try-with-ai");

const [err, data] = safeTryJson('{"x":1}', { analyze: true });

if (err) {
  console.error(err);
}

---

CLI Usage

Validate JSON files from the terminal:

npx safe-try-with-ai example.json
npx safe-try-with-ai example.json --analyze

Pipe JSON via stdin

cat example.json | npx safe-try-with-ai --stdin
cat bad.json | npx safe-try-with-ai --stdin --analyze

STDIN support (v1.5.0+)

Validate JSON from pipes:

cat file.json | safe-try-with-ai --stdin -a

CLI Output Legend

• ✔ JSON valid (green)
• ✖ JSON invalid (red)
• Suggestions (blue)
• Fix (green)

Exit Codes

• 0 = valid JSON
• 1 = invalid JSON or runtime error

---

TypeScript Support

Built-in TypeScript definitions included:

import { safeTry } from "safe-try-with-ai";

const [err, result] = safeTry(() => JSON.parse(data));

No configuration required.
