I tried to used consolidate package with gulp to build the MEAN stack app. But I don't know why when I run npm install, then gulp browserify, it always threw a lot of exceptions like

I guess that something wrong in consolidate package, because it did not install package recursively. My consolidate version that I used is 0.12.1. Anyone can help me?
Consolidate does not contain any template engine. You should install them on your level.
I guess you are using hogan templates, so you need to install it. Run this in your project root
npm install hogan.js --save

I am attempting to display an Axis camera live stream in my Next.js front-end after making a request to the Axis API in my custom Node.js server. After making this request
const response = await client.fetch(`http://${ip}/axis-cgi/mjpg/video.cgi?resolution=${resolution}&fps=${fps}&compression=${compression}`, {
method: 'GET',
headers: {
'Content-Type': 'multipart/x-mixed-replace; boundary=--myboundary',
},
});
I get a response with the status code of 200 and the following in the response body:

My question is how do you use this data to display the MJPEG on the front-end? Originally, I was passing the URL to an img tag, but this approach does not work in production as the URL is not secure.
OK. I've never done it this way but after a quick googling around I think it's possible to do what you want. So for next.js you can do the following:
WARNING: Untested code
Create an API endpoint for your MJPEG stream.
From the answer to this question (multipart/mixed response using NodeJS) it looks like in the handler you can pipe the fetch response to the res object (assuming that your client.fetch function implements the fetch API).
function handler(req, res) {
const response = await client.fetch(url, options);
response.body.pipeTo(res);
}
On the client side just set the src property of an img tag to the URL of your API endpoint. You can protect the API endpoint with session cookies or a session hash in the URL but using Authorization header won't work because the img tag cannot set custom headers in its request.
I am trying to upload multiple files from sailsjs 1.2.4
Here is my action :
module.exports = {
friendlyName: 'Post',
description: 'Post something.',
files: ['mediaFiles'],
inputs: {
text : {
required: true,
type: 'string',
},
mediaFiles : {
description : "Media files",
example: '===',
required : false
}
},
exits: {
},
fn: async function (inputs) {
inputs.mediaFiles._files.forEach(file=>{
console.log(file)
})
})
}
}
I am getting below result in as file object :

My question is how can I write this file stream to some path like /public/media/xyz.png . I used to with sails normal file upload where I can use this.req.file("name").upload() .. but not in action 2 . I checked other answers but they are uploading to s3 not writing on same server .
You could use a dependency sails-hook-uploads, for that you are able to define the dirpath in your settings:
https://github.com/sailshq/sails-hook-uploads/blob/master/index.js#L31
module.exports.upload = {
dirpath: '.tmp/public', // recommended .tmp/uploads
adapter: require('skipper-disk'), // Default
}
I highly recommend not using the public folder because it's the compiled assets destination, so you'll probably lose these files.
As an alternative, you might use a controller to upload the file as showing below:
https://github.com/mikermcneil/ration/blob/master/api/controllers/things/upload-thing.js#L54
After that, send it to the user:
https://github.com/mikermcneil/ration/blob/master/api/controllers/things/download-photo.js#L50
I am trying to search my documents indexed on solr 6.6.5 using facet search in node.js with the solr-node module. But when I add facet=on&facet.query=: I get an HTTP 400 response from solr-node.
var client = new SolrNode({
host: 'localhost',
port: '8983',
core: 'IRF18P4',
protocol: 'http',
debugLevel: 'ERROR' // log4js debug level paramter
});
var delhiCount = client.query.q('*:*&facet.query=city:delhi&facet=on');
// Search documents using strQuery
client.search(delhiCount, function (err, result) {
if (err) {
console.log(err);
return;
}
console.log('Response:', result.response);
});
But if I try to open the same URL printed in my terminal, it works. Any idea on what could be going wrong here?

I am using the node js module util and including it in my project like so:
var util = require('util');
When I return the response like so:
util.inspect(response, false, null);
I get this output:

How do I get the value of text to output?
Shouldn't it be:

I want to read a file line by line and based on the data in each line i have to categorise the data.
var rd = readline.createInterface({

});
When this line is executed the file is read and printed in the terminal.
But when I try to read the file line by line using readline I am getting error.
rd.on('line', (input) => {
console.log(input);

Please help I am new to this.
Your code looks fine but you are using the Node.js REPL rather than running the code from a file, which is why you're seeing this behaviour.
The Node.js REPL (what you get when you type node in terminal) will store variables. However, when only an identifier is used the value is also returned. What you're seeing isn't an error, but the rd object.
The Node.js REPL is good for testing but, unless you have a specific reason for using it, the best thing to do is create an app.js file, add your code to it and then run node app.js.
If you do need to write multi-line code using REPL, then be sure to type .editor once initialised, so that whitespace, etc. is interpreted correctly.
Also, from the 7.7.2 docs console isn't an option which createInterface is expecting, so that can be removed. In your particular example, you could also remove output: process.stdout, as your logging each line using the line event
