Unleash features and specs

  • Flexibility
    Unleash provides a highly flexible feature management system that allows teams to enable or disable features without deploying new code. This is particularly useful for A/B testing, gradual rollouts, and quick feature toggles.
  • Open Source
    Being an open-source platform, Unleash allows you to review the source code, contribute to improvements, and avoid vendor lock-in. This provides a greater degree of transparency and control.
  • Multiple Environment Support
    Unleash supports multiple environments (development, staging, production) out of the box, enabling seamless management of feature releases across different stages of software development and deployment.
  • Strong Community
    As an open-source project, Unleash boasts a strong community that contributes to its constant improvement and provides support through forums, documentation, and other channels.
  • Privacy and Security
    Unleash allows self-hosting, which can be a significant advantage for organizations concerned about data privacy and security. Self-hosting ensures that no feature flag data leaves your infrastructure.

GatsbyJS features and specs

  • Performance
    GatsbyJS pre-builds your site into static files for fast load times and instantaneous page loads thanks to features like code splitting, PRPL pattern, and Asset Optimization.
  • SEO-Friendly
    GatsbyJS generates static HTML, which helps search engines to index your site more effectively. Additionally, you have fine-grained control over metadata and other SEO optimizations.
  • Rich Plugin Ecosystem
    GatsbyJS boasts an extensive plugin ecosystem that covers a wide array of functionalities such as sourcing data from CMSs, adding analytics, integrating with various APIs, and much more.
  • Strong Community Support
    Gatsby has a robust and active community that provides ample documentation, tutorials, and support to help you get started and troubleshoot issues.
  • Secure and Scalable
    Since Gatsby sites are static, they are inherently more secure against traditional web-based vulnerabilities and can be scaled easily by deploying to a CDN.

Possible disadvantages of GatsbyJS

  • Build Time
    For larger sites, build times can become noticeably long as Gatsby rebuilds the entire site. This can be a bottleneck for frequent updates.
  • Less Suitable for Dynamic Content
    Since Gatsby generates static pages, it's less suited for applications that require real-time data updates or dynamic content unless they are integrated with client-side JS or third-party services.
  • Initial Setup Complexity
    Getting started with Gatsby can be complex for beginners unfamiliar with React and GraphQL, as it requires knowledge of these technologies.
  • GraphQL Learning Curve
    A significant part of customizing and extending Gatsby sites involves GraphQL queries, which can be a barrier for developers who are not yet familiar with GraphQL.
  • Plugin Quality Variability
    While Gatsby has a rich plugin ecosystem, the quality and maintenance of plugins can vary, requiring developers to vet the plugins they choose to integrate into their projects.

  • KILLSWITCH
    So my first instinct is to setup some sorta feature-flag thing within a CMS so managers can flip the boolean, I'm exploring getunleash.io and GrowthBook.io and we already use Contentful.com within the app but they're saying they "really don't think we need to use any third party thing for a killswitch"...

    TLDR: Privacy is really important for us at Unleash. Here you will find the full story on how we ended up with an analytics solution that does not collect personal data and has very short retention. Whenever we evaluate a new feature at Unleash, we always start with one question. How does this fit with our values? This question is powerful. It can quickly qualify or disqualify a feature from consideration, putting... - Source: dev.to / almost 3 years ago

    I'd start with learning HTML and CSS first, then Javascript after those. There are a lot of free online resources for learning those. For websites, I use jekyll which is a great way to start off because there are a lot of community website templates that you can customize, which is great for beginners and learning. Then I'd recommend learning/moving to React. The Gatsby website generator would be good for React... Source: over 2 years ago
