What is the proper way to check for existence of variable in an EJS template (using ExpressJS)?


node.js express ejs

The same way you would do it with anything in js, typeof foo == 'undefined', or since "locals" is the name of the object containing them, you can do if (locals.foo). It's just raw js :p

node.js express ejs

Try prepending the variable with locals

Example: if(locals.user){}

node.js express ejs 

<% if (locals.user) { %> // Your logic goes here <% } %>
