You can. An Arranged Marriage By Jo Beverley Pdf Printer. json files. Var parsedJSON = require('./file-name'); For example if you have a config.json file in the same directory as your source code file you would use: var config = require('./config.json'); or (file extension can be omitted): var config = require('./config'); note that require is synchronous and only reads the file once, following calls return the result from cache Also note You should only use this for local files under your absolute control, as it potentially executes any code within the file. @natario: We are talking about server-side JS here. Suppose someone is parsing user-supplied JSON. If the assumption is that the JSON is always well formed, an attacker can send some malformed JSON to trigger an error, which if spilled to the client side, may reveal vital information about the system. Or if the JSON was both malformed and contained some text with.

For example, I want to build a big Library on my computer, then serialize it, put on a file, send the file to another computer, deserialize it there, and have the exact same Library. Node.js serialization polymorphism. Serialize an object including it's function into a JSON. - luin/serialize.

As other answers here have mentioned, you probably want to either require a local json file that you know is safe and present, like a configuration file: var objectFromRequire = require('path/to/my/config.json'); or to use the global JSON object to parse a string value into an object: var stringContainingJson = ' 'json that is obtained from somewhere '; var objectFromParse = JSON.parse(stringContainingJson); note that when you require a file the content of that file is evaluated, which introduces a security risk in case it's not a json file but a js file. Here, i've published a demo where you can see both methods and play with them online (the parsing example is in app.js file - then click on the run button and see the result in the terminal): you can modify the code and see the impact.

These prepended values have null bytes on either side. DO NOT serialize data and place it into your database. Serialize can be used that way, but that's missing the point of a relational database and the datatypes inherent in your database engine. Doing this makes data in your database non-portable, difficult to read, and can complicate queries. If you want your application to be portable to other languages, like let's say you find that you want to use Java for some portion of your app that it makes sense to use Java in, serialization will become a pain in the buttocks.

You should always be able to query and modify data in the database without using a third party intermediary tool to manipulate data to be inserted. I've encountered this too many times in my career, it makes for difficult to maintain code, code with portability issues, and data that is it more difficult to migrate to other RDMS systems, new schema, etc. It also has the added disadvantage of making it messy to search your database based on one of the fields that you've serialized. That's not to say serialize() is useless. A good place to use it may be a cache file that contains the result of a data intensive operation, for instance. There are tons of others.
