i know blocking code discouraged in node.js because single-threaded. question asking whether or not blocking code acceptable in circumstances. for example, if running express webserver requires mongodb connection, acceptable block event loop until database connection established? assuming pages served express require database query (which fail if mongodb not initialized). another example application requires contents of configuration file before being initializing. there benefit in using fs.readfile on fs.readfilesync in case? is there way work around this? wrapping code in callback or promise best way go? how different using blocking code in above examples? it decide acceptable. , determining consequences of blocking ... on case-by-case basis. analysis take account: how occurs, how long event loop blocked, and the impact blocking in context have on usability 1 . obviously, there ways avoid blocking, these tend add complexity application. really, nee...
