问题 I am uploading the images from an IOS application to Firebase which returns to me the metadata including the URL of type URL . Should I store it of type String in the database like below code? or there is specific type for URL s? var schema = new Schema({ downloadURL: { type: String, createdDate: Date.now } }) 回答1: Well, As per the docs Monngoose doesn't have a schema type for URL. You could just use a string with RegExp to validate it or use some custome made type like this one var mongoose

问题 I have Joi schema and want to add a custom validator for validating data which isn't possible with default Joi validators. Currently, I'm using the version 16.1.7 of Joi const method = (value, helpers) => { // for example if the username value is (something) then it will throw an error with flowing message but it throws an error inside (value) object without error message. It should throw error inside the (error) object with a proper error message if (value === "something") { return new Error

问题 I'm using the 'adal-node' npm package to authenticate with an AzureAD. This is all working fine and I get a token back. However, the when examining the 'aud' claim in the JWT token I see the audience GUID is prefixed with 'spn:'. I think this is causing me problems when I try to use the JWT token on an already existing Web API. When I authenticate via a WebApp using the same AzureAD the 'aud' claim is NOT prefixed with 'spn:' and I am able to called endpoints on the WebAPI. Can anyone shed

问题 I've just installed nodejs on Debian 7 - by apt-get install nodejs. Nodejs seems to be working fine, but when I enter "npm" I get "command not found".

If you want to continue using Debian packages, you could

问题 Edit : Node uses bytecode since Node 8.3, before that, sources were compiled directly to machine code. I do a lot of Python coding, and there's always bytecode lying around in .pyc files. I was wondering if node stores its machine code in similar files, eg it would make sense to keep the machine code representation around on disk and re-use it if a file's source is unchanged. If so, where does node/v8 store this machine code? Edit 2 : As @dystroy mentions below this is a dupe of How can I see

问题 I wrote a simple npm module to precompile my handlebars templates when using django compressor to do post-processing for some client side components and found that I need to ship the npm module with a few js files. Currently I just assume no one is installing this with the global flag because I've "hard coded" the path to these dependencies in the npm module itself example layout of my npm module / * /bin * /lib/main.js * /vendor/ember.js Now inside main.js I want to use the ember.js file ...

问题 Im building an iOS app that have a view that is going to have its source from markdown. My idea is to be able to parse markdown stored in MongoDB into a JSON-object that looks something like: { "h1": "This is the heading", "p" : "Heres the first paragraph", "link": { "text": "Text for link", "url": "http://exampledomain.com", } } On the server I am running Node.js, and was looking at the module marked which seem to be the most popular one out there. It gives me access to the Lexer, which is

问题 I want to be able to use my React app to make a GET request to my server, which is suppose to prompt my server to make an GET request to an external API. I'm using axios and tried using request but both are giving me ERRTIMEOUT.
