Node.js light weight module to apply specific load to a REST API and obtain the statitics
Light weight Node.js module to apply specified load on a REST API and retrieve the response statistics. I gives the counts of good,bad and errored responses along with the time taken to process them all.
npm install node-stress
var stress = require("node-stress");
stress({
host: url, //strip off the starting http:// same as in case of node http request
port: port,
path: path
},RequestCount,callback);
var stress = require("node-stress");
stress({
host: 'rest.api.url',
port: 80,
path: '/getData.php?command=1'
},RequestCount,function(data){
console.log("Requests Sent : "+data.ReqStarted);
if(data.response.GoodResponse)
console.log("Good Response (200 OK) : ", data.response.GoodResponse);
if(data.response.BadResponse)
console.log("Bad Response : ", data.response.BadResponse);
if(data.response.ErrorResponse) {
console.log("Error Response : ", data.response.ErrorResponse);
console.log(JSON.stringify(data.response.ErrorList,undefined,4));
}
console.log("Test Stats : "+data.fact);
});
host - the url of the REST API after stripping down the starting http://. For more info check the input parameter for the node sample http request.
port - port at which the REST API runs
path - path to the page we are sending request
RequestCount - the load to be applied in number (eg:1000)
