node.js

问题 I have created some standard middleware with some logic, and depending on the logic I need to call some 3rd party middleware. Middleware is added using app.use(), which is where I add my custom middleware. Once in my middleware I no longer have access to app.use(), how do I call the middleware? Here is some code: Any ideas ? const customerData = (req, res, next) => { try { console.log('Started'); if (process.env.STORE_CUSTOMER_DATA === 'true') { // Here is some custom middleware that doesn't

问题 Is there any existing technique or npm package that can prevent all outgoing requests from a NodeJS server, allowing only responses to incoming requests? This could prevent phone-home type attacks in deep dependencies missed in security audits. 回答1: A firewall. That's truly the only way. Remember though that there is nothing stopping some code from accepting commands from clients connecting to it. 回答2: Have a look at http://www.cyberciti.biz/tips/block-outgoing-network-access-for-a-single

问题 I pass a config file to another node.js module when starting it. The config file contain the following json: "resolution": { "activated": true, "types": [ {"of": 23} ] } When I print the received types array in the called node.js module, it looks like console.log('types array: '+ this.config.resolution.types) //output types array: [object Object] if I tried to print the text by using JSON.stringify() , I get the following result [{"of":23}] My problem start when I try to replace the types

问题 I am trying to get all the items in a flat dataset that are grouped together to form a hierarchical dataset using Javascript/Node.JS. I have a solution, but I don't think it's the most elegant and it could probably be improved. I based my solution of the answer here Find all objects with matching Ids javascript My dataset is as follows: let data = [{cid: 1, clbl: 'Rush Shipping', pid:5, plbl: 'FedEx'}, {cid: 2, clbl: 'Standard Shipping', pid:5, plbl: 'FedEx'}, {cid: 3, clbl: 'First Class',

问题 I am trying to send a lot of https requests and processing that causes my code to crash. I know I can increase my memory but that won't scale. Uncommenting the code below causes OOM crash at some point. The solution should probably be to flush the buffer or something, but I am learning nodejs so not sure what to do. var https = require('https'); // url anonymized for example var urlArray = ["https://example.com/blah", ....] // 5000 urls here var options = { headers: { "x-api-key": "mykey" } }
