loopbackjs - LoopBack Vs Breeze.JS to use with Node.JS -

-

are both loopback , breeze.js same persist data node.js client applications database mssql, oracle etc...?

loopback exciting company smart people.

i don't know loopback's data management offerings and, 1 of principals behind breeze, don't feel comfortable making comparisons anyway.

i think it's wise consider every technology choice in context of broad business , application needs.

let me suggest areas investigate:

  • what database(s) care about? how product work databases?

  • do need/want support on server for

    • transactions
    • validation during save
    • batch save requests (mix of entity types , insert/update/delete)
    • batch query requests

  • do need/want support on client for

    • client-side caching , events
    • tracking entity change state
    • property change notification
    • property , entity validation
    • automated entity graphs (e.g. just-in-time population , maintenance of entity navigation properties)
    • typed representation of sub-documents ("complex types")
    • original value tracking (ability cancel pending changes)
    • serialization of entity graphs circular references.

  • will need consider integration non-node client or server technologies? legacy applications , services?

  • is there both developer , api documentation? how much? provide kind , quality of guidance you'll need?

  • how many questions have been asked on stackoverflow? questions people asking technology on stackoverflow? kinds of questions you'll asking build app? think of answers?

  • what require of customer support for specific technologies seek?

  • how established , stable technology seek? vendor well-versed in issues , concerns of trying solve these problems? matter you?

  • what people doing technology? beyond customer list. find out whether these customers doing want do.

  • what vendor's experience designing , supporting kinds of applications intend build technology?
