Title: An%20Introduction%20to%20Fusebox%204


1
An Introduction to Fusebox 4
  • If written directions alone would suffice,
    libraries wouldn't need to have the rest of the
    universities attached.
  • Judith Martin (aka "Miss Manners")

2
State of Fusebox
  • The last two years have seen
  • increased corporate acceptance of Fusebox
  • increased developer acceptance of Fusebox
  • increased demand in job postings for Fusebox
  • no new version of Fusebox

3
Fusebox What's in it for the client?
  • Less risk in software projects
  • Greater "project visibility"
  • Not locked into a non-standardized framework

4
Fusebox What's in it for managers?
  • Reduces costs of deployment
  • Reduces cost of tools and training
  • Allows better allocation of resources

5
Fusebox What's in it for me?
  • Helps good programmers produce great results
  • Lets you distinguish yourself from your
    competition
  • Helps stop the madness

6
FB4 It's all new!
  • XML file defines overall application parameters
    Fusebox.xml
  • XML file defines individual circuits Circuit.xml
  • a permissions attribute for fuseactions
  • Plugins allow developer extensions of core
    Fusebox
  • Content components
  • Change in way layouts are handled
  • Parsing cycle

7
FB4 It's just the same!
  • Core files process a fuseaction request
  • Circuits provide logical groupings of fuseactions
  • Fuses hold the code
  • dsp for display
  • act for action
  • qry for query
  • lay for layout

8
Building a simple FB4 app

20
Write test harnesses!!!
  • Make sure that all your fuses fulfill their
    contract
  • For this, you will need to use the Fusedocs

21
Define how/what fuseactions the Users circuit
will handle circuit.xml
  • ltcircuit access"public"gt

28
The Fusebox grammar
  • include
  • ltinclude template"dspProducts" /gt
  • set
  • ltset name"dsn" value"FruitProducts" /gt
  • xfa
  • ltxfa name"success" value"home.main" /gt
  • do
  • ltdo action"home.listProducts" /gt
  • relocate
  • ltrelocate url"http//techspedition.com" /gt
  • if
  • loop

29
Good Stuff in Fusebox 4
  • Language/version-neutral syntax
  • Extensibility through plugins
  • Improved performance
  • No gut-wrenching changes
  • Can execute multiple fuseactions in same HTTP
    request (reduces ltcfmodulegt calls)
  • Very flexible content components
  • Less need to understand the Fusebox API
