I'm working on a project using express with mustache templates, I'm trying to pass object to the template using res.locals but it's not working,
this is the code
exports.menu = function(req,res){
res.locals.title = "Menu";
res.locals.class_type ="main_nav";
MenuDB.GetAvailableLunch()
.then((list) => {
res.locals.lunch = list;
console.log('Promise Resolved');
})
.catch((err) =>{
console.log('Promise rejected', err);
})
res.render('menu');
}
I want the list that comes from the function to be the lunch object which I have on the mustache page, any ideas how to do this? I know that I can just do it like this
.then((list) => {
res.render('menu', {
'lunch': list
});
but I'm trying to do it this way because I will have another function to return another lists from the database, hope this is clear enough.
Build a promise-chain or array of independent promises and only call res.render() once everything is resolved.
For example...
exports.menu = async (req, res) => {
const [lunch, another] = await Promise.all([
MenuDB.GetAvailableLunch(),
anotherFunction(),
]);
res.render("menu", {
title: "Menu",
class_type: "main_nav",
lunch,
another
});
};
