Error in development mode: req.session.returnTo = req.path; about typescript-node-starter

Hey,
it means, that TS node configuration is not including 'express-session-types',
you need make sure 'express-session-types' are included in your compilation. My guess is tsc resolves 'express-session' only to 'node_modules/@types/express-session' and no declaration is read from 'express-session-types'

[peterblazejewicz]

in your current project, make sure the code that augments 'express-session' (adding 'returnTo') is included, e.g. you can import this code into entry module. The case is to force 'tsc' to properly resolve 'express-session' first (@types/express-session) and next 'express-session' augmentation code. This setup has to work for both regular and 'ts-node' setup. 'ts-node'' has special syntax to resolve deps properly (e.g. to read dedicated tsconfig). I think this is the problem. The example here ('express-session-types') is use-case specific example on how to incorporate 'returnTo' property.

Thank you very much for this resolution, indeed the solution was to force the import within the app.ts file in the following way. ❤️

import * as sessionTypes from './types/express-session-types';

Indeed, but when doing it either with typeRoot or including the types, it takes by default the ones from the types folder inside the src and not the node_modules, sometimes the express-session call inside the app.ts file has no effect because it is not callable.

When trying to do the following

app.use(session({
    resave: true,
    saveUninitialized: true,
    secret: SESSION_SECRET,
    store: new MongoStore({
        mongoUrl,
        mongoOptions: {
            autoReconnect: true
        }
    })
}));

The following error occurs, so even if the call to the types is made, the execution in development mode still does not work.

This expression is not callable.
