@ashkiani/express-responses v1.0.0

express-responses

Reusable response helpers for Express APIs with integrated logging support — standardize your JSON/text replies and HTTP error handling with one module.

@ashkiani/express-responses

Reusable HTTP response helpers for Express APIs — with optional structured logging.

This utility standardizes how your Express app sends JSON, text, and error responses. It also supports logging response details (e.g., status codes and payloads) when a log object is available.

📦 Installation

npm install @ashkiani/express-responses

🛠 Usage

1. Import the module:

const resUtils = require('@ashkiani/express-responses');

2. Use it in your route handlers:

app.get("/api/example", async (req, res) => {
    const logEntry = {
        requestId: "abc123",
        timestamp: new Date()
    };

    try {
        await resUtils.sendJsonResponse(res, 200, { message: "Success!" }, logEntry);
    } catch (err) {
        await resUtils.send500InternalError(res, logEntry);
    }

    // Optional: Save logEntry to DB
});

📘 API Reference

sendTextResponse(res, statusCode, message, logEntry?)

Sends plain text and, if a logEntry object is provided, logs the response.

sendJsonResponse(res, statusCode, jsonObj, logEntry?)

Sends JSON and logs it if a logEntry object is present.

send204NoContent(res, logEntry?)

Sends a 204 No Content response.

Predefined Error Responses

These are convenience wrappers for common error statuses:

Each function accepts (res, logEntry?) and safely logs the response if logEntry is provided.

💡 Notes

• Logging is optional. If logEntry is omitted, the function still works without throwing errors.
• These helpers work well with any logging system — just ensure your logEntry object includes a response field if you want to store response details.
• Compatible with @ashkiani/mongo-logger for full request-response auditing.
