Single Page Application Consulting

Single Page Applications (SPA) allow the enterprise to provide users with rich, responsive applications through the browser. This creates extensive cost savings; gone is the necessity to develop for multiple platforms to reach users on multiple operating systems.

SPA provides the following benefits:

  • Mobility support
  • Plugins eliminated
  • Cross-browser support
  • Rich, responsive user experience leveraging the benefits of HTML5

Keyhole Software has extensive expertise with development utilizing SPA architectures with JavaScript and HTML5. From technology selection and adoption, to adapting current data and business logic to this new architectural approach, to teaching your team how to effectively implement these technologies themselves — Keyhole Software has your organization covered.

Enterprise SPA Adoption Services

SPA JavaScript MV* Selection and Adoption

There are many viable MV* frameworks and they all have their strengths. Deciding which framework suits your enterprise is a function of leveraging application UI requirements and existing developers’ competency in JavaScript. We at Keyhole Software have our lineage in classical-based object-oriented development and have helped enterprises successfully transition to many MV* JavaScript frameworks. We can help you justify and establish a team development environment, providing the education necessary to fill in the gaps.

Here are a few mechanisms and patterns we can help put in place, no matter what the chosen MV* framework is:

  • Sharing common vendor JS libraries
  • Project Structure / Modularity / Namespace conventions
  • Transparent API Mocking
  • Unit Testing
  • UI Validation, client and server-based
  • Bundling and sharing internal JS libraries
  • Optimizing client side SPA resources
  • Logging / Tracing local and remote for support
  • Reference application and / or usage patterns
  • Authentication and applying of role-based ACLs (Access Control Lists)

Our teams have extensive real-world enterprise development experience with Backbone.js, Angular.js, and ExtJS, and have successfully implemented these technologies in multiple business domains.

Adapting Server Side Data and Business Logic to RESTful API-based Architecture

SPA requires a fundamental application architecture shift. If existing .NET/Java technology stacks are still viable, they need to be repurposed for a more lightweight API-based access on the client (browser) side.

Enterprises with existing Java EE or .NET infrastructures can easily adapt to SPA support by introducing a RESTful-based API framework to application servers. Java EE can adapt servlet-based frameworks, such as Spring MVC, Jersey, or Sherpa, while .NET can introduce WebAPI, MVC.Net, or WCF. This choice depends upon application requirements and the frameworks currently available in the enterprise.

Here are some patterns and mechanisms that will need to change to support API development for SPAs:

  • RESTful API endpoint implementation
  • Application data access strategy
  • Endpoint authentication and access control mechanism
  • Versioning endpoints
  • Testing endpoints
  • Effective API design
  • Effective API payload design
  • Transactions
  • Data concurrency
  • Validation / Error handling
