Express and i18n

[michaelpastushkov]

Better support for i18n is needed inside pug templates. For now I found the solution but it's a bit complex and confusing. I though pug processor is one of the natively supported engines for i18n.

Pug Version: "^3.0.2",
Node Version: v14.15.4

Input JavaScript Values

// server level
app.use(function(req, res, next) {
// express helper for natively supported engines
i18n.init(req, res);
res.locals.__ = res.__ = function() {
return i18n.__.apply(req, arguments);
};
next();
});

// Module level
const pug = require('pug');
const func = pug.compileFile('pug/test.pug');
function foo(req, res) {
let msg = res.__('Hello');
let ins = func({ message: msg, : res. }); // << I have to add this to every render request
res.end(ins);
}

Input Pug

p #{msg}
p #{__('Hello')}

Expected HTML

Localised output (based on browser locale)

Actual HTML

I finally made it work, but there should be an easier way to do it.
