bearcat-jstrace

jstrace support for bearcat based on bearcat AOP

Installation

npm install bearcat-jstrace --save

update context.json, add bearcat-jstrace dependencies

"dependencies": {
    "bearcat-jstrace": "*"
}

Usage

bearcat-jstrace uses bearcat AOP as its backbone, the default pointcut defined is

"pointcut": "around:\\w+Service.*?",

therefore all your POJOs' methods named with Service will be traced by jstrace

you can overload this pointcut by setting up context.json in your project like

"beans": [{
    "id": "jstraceAspect",
    "func": "node_modules.bearcat-jstrace.lib.aspect.jstraceAspect",
    "aop": [{
        "pointcut": "around:\\w+Dao.*?",
        "advice": "doJstrace",
        "runtime": true
    }]
}]

this changes to all POJOs' methods named with Dao will be traced by jstrace

you can set up trace target by add traceName in your trace target like

HelloService.prototype.traceName = "HelloService";

note: since the best practise of AOP target method is a function with callback function, when it is a sync function with return, end trace will not be emitted
