Is Sprout production-ready?

Sprout is still in development towards v1.0, so while it's stable for testing, production use requires caution due to potential breaking changes. Monitor the roadmap for stability updates.

How do I migrate from Sprig to Sprout?

Use the sprigin package for a drop-in replacement by swapping imports, but the README recommends updating to Sprout's native functions for new features. Refer to the migration guide in the documentation.

Sprout vs Sprig: which is better for new projects?

Choose Sprout for better performance, modern Go compatibility, and active maintenance. Sprig is only suitable if you're locked into an older Go version and don't need updates.

How to add custom functions to Sprout?

Create a custom registry by implementing the Registry interface and add it to the handler with AddRegistry. Check the documentation for examples on extending functionality.

Does Sprout support HTML templates in Go?

Yes, Sprout works with both text/template and html/template packages. Build the function map using handler.Build() and pass it to the template's Funcs method for rendering.

What are Sprout's performance benchmarks?

Sprout shows a 45.3% speed improvement and 16.5% memory reduction over Sprig v3.2.3, as detailed in the README's benchmark section. Full results are available in the benchmarks directory.

What is sprout?

Sprout is a template function library for Go that provides a rich set of utility functions for use with Go's `text/template` and `html/template` packages. It serves as a modern, maintained alternative to the Sprig library, offering enhanced performance, compatibility with recent Go versions, and additional functionalities. The project solves the problem of Sprig's stagnation by delivering an actively developed library optimized for contemporary Go development.

Target Audience

Go developers who need advanced template functions for generating text or HTML output, particularly those migrating from Sprig or starting new projects requiring robust templating capabilities.

Value Proposition

Developers choose Sprout over alternatives because it is actively maintained, significantly faster and more memory-efficient than Sprig, fully compatible with modern Go versions, and offers a seamless migration path via backward compatibility. Its modular registry system and customization options provide flexibility without sacrificing performance.

Overview

From sprig to sprout - Useful template functions for Go templates with steroids

Use Cases

Best For

Migrating from Sprig to a maintained library
Building high-performance text or HTML templates in Go
Adding advanced string manipulation and logic functions to templates
Creating modular template function sets with registries
Ensuring compatibility with Go 1.13+ versions
Optimizing template rendering speed and memory usage

Not Ideal For

Projects using non-Go templating engines like JavaScript frameworks or Python's Jinja2
Teams that want a simple, drop-in function map without handler configuration and registry management
Applications requiring template functions with heavy external dependencies or API integrations, as Sprout avoids dependencies for self-contained operations

Pros & Cons

Pros

Superior Performance

Benchmarks show Sprout is approximately 45.3% faster and uses 16.5% less memory than Sprig v3.2.3, making it ideal for high-throughput template rendering.

Modern Go Compatibility

Fully compatible with the latest Go versions, unlike Sprig which was stuck at Go 1.13, ensuring long-term support and stability.

Seamless Migration Path

Includes a sprigin package for drop-in replacement of Sprig functions, easing the transition for existing projects without immediate code changes.

Modular and Flexible Design

Functions are organized into registries and groups, allowing developers to include only what they need and optimize template performance through selective loading.

Cons

Pre-Release Instability

Still on the roadmap to v1.0, meaning API changes and potential breaking updates are likely until the official release, as noted in the documentation.

Configuration Overhead

Requires creating a handler and managing registries, adding complexity compared to Sprig's straightforward FuncMap() approach, which may deter users seeking simplicity.

Limited Ecosystem

As a newer project, it has fewer third-party resources, plugins, and community support compared to established alternatives like Sprig, which could slow adoption.
