UPDATE: (5 years later) Note: If you decide to use Kappa Architecture (Event Sourcing + CQRS), then you do not need updated date at all. Since your data is an immutable, append-only event log, you only ever need event created date. Similar to the Lambda Architecture, described below. Then your application state is a projection … Read more
Check the NPM docs for install With the –production flag (or when the NODE_ENV environment variable is set to production), npm will not install modules listed in devDependencies.” The –only={prod[uction]|dev[elopment]} argument will cause either only devDependencies or only non-devDependencies to be installed regardless of the NODE_ENV.” Have you tried npm install –only=dev If you are … Read more
If you NPM those modules you can serve them using static redirect. First install the packages: npm install jquery npm install bootstrap Then on the server.js: var express = require(‘express’); var app = express(); // prepare server app.use(‘/api’, api); // redirect API calls app.use(“https://stackoverflow.com/”, express.static(__dirname + ‘/www’)); // redirect root app.use(‘/js’, express.static(__dirname + ‘/node_modules/bootstrap/dist/js’)); // … Read more
I’ve had the same problem you describe. The web site I’m building can be accessed from a mobile phone and from the browser so I need an api to allow users to signup, login and do some specific tasks. Furthermore, I need to support scalability, the same code running on different processes/machines. Because users can … Read more
If you are using aws-sdk with version > 2.x, you can tranform a aws.Request to a promise with chain .promise() function. For your case: try { let key = await kms.generateDataKey().promise(); } catch (e) { console.log(e); } the key is a KMS.Types.GenerateDataKeyResponse – the second param of callback(in callback style). The e is a AWSError … Read more
EDIT – Query performance: As @NeilLunn pointed out in his comments, you should not be filtering the documents manually, but use .find(…) for that instead: db.snapshots.find({ roundedDate: { $exists: true }, stream: { $exists: true }, sid: { $exists: false } }) Also, using .bulkWrite(), available as from MongoDB 3.2, will be far way more … Read more
It’s not an issue with model export. I had the same issue. The real issue is that require statements for the models var mongoose = require(‘mongoose’); mongoose.connect(‘mongodb://localhost/news’); require(‘./models/Posts’); require(‘./models/Comments’); were below the routes dependencies. Simply move the mongoDB dependencies above the routes dependencies. This is what it should look like: // MongoDB var mongoose = … Read more
A unique index on an array field enforces that the same value cannot appear in the arrays of more than one document in the collection, but doesn’t prevent the same value from appearing more than once in a single document’s array. So you need to ensure uniqueness as you add elements to the array instead. … Read more
You can use this to delete its entry in the cache: delete require.cache[require.resolve(‘./b.js’)] require.resolve() will figure out the full path of ./b.js, which is used as a cache key.
The easy solution is just switch from the “bcrypt” npm module to bycryptjs or bcrypt-nodejs. It’s the exact same API, but pure JS so no native add-ons to deal with. npm install –save bcryptjs && npm uninstall –save bcrypt Then change your require calls to “bcryptjs”, but all your code otherwise can be unchanged. Long … Read more
