• [x] Error observe, includes js error, unhandle rejection error and http error
• [x] Error filters and error sampling
• [x] Slow http request observe
• [x] Observe user behaviors into a behavior queue
• [x] Performance observe for every page

Install

NPM

npm i femonitor-wx -S

Usage

const { Monitor } = require("femonitor-wx");

/* Options could be undefined because SDK has default options  */
const monitor = Monitor.init(options);

/* Listen all event */
monitor.on("event", (eventName, emitData) => {
  /* Use wx.request to report data here  */  
  console.log(eventName, emitData);
});

DefaultOptions

Options param will be deepmerge into defaultOptions

export const defaultOptions = {
  env: Env.Dev,   
  isSystemInfo: true,  // If get system info
  isNetwork: true,     // If get network info
  httpTimeout: 0,      // Define slow httptimeout(ms)
  error: {
    filters: [],       // Filter error using regexp array
    random: 1          // Extract error samples, 1 is 100%
  },
  behavior: {
    isFilterConsole: false,  // If record console behavior
    queueLimit: 20,          // Limit behavior queue to 20
    // Observe function name includes methodWhilteList, priority is higher than methodBlackList
    methodWhiteList: [],
    // Observe function name excludes methodBlackList
    methodBlackList: []
  },
  performance: {
    watch: true,       // If watch page performance
    queueLimit: 20     // Limit performane queue to 20
  }
};
