Enterprise Adoption Considerations


SPA JavaScript MV* Selection and Adoption

There are many viable MV* frameworks and 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.

Patterns To Implement

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 React, React Native, Vue.js, Backbone.js, Angular.js, Angular 2+,  and others, 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 or .NET infrastructures can easily adapt to SPA support by introducing a RESTful-based API framework to application servers. Java can adapt servlet-based frameworks, such as Spring MVC while .NET can introduce Web API.

Change To Support API Development

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

Through our partnerships with leading software vendors and extensive experience with various clients and industries, we maintain a broad range of business application competencies.
