Why would you pass i18n instance from backend to frontend via ctx.req #209

Closed zhangyugege closed 4 years ago

Hello ~ I see that the middleware on the node server depends on the i18n-express-middleware library.

In i18n-express-middleware, it pass the entire i18n example to the front end via ctx.req.

    // assert for req
    req.i18n = i18n;
    req.t = t;

Source code at: https://github.com/i18next/i18next-express-middleware/blob/master/src/index.js#L60

Why would you pass the entire i18n instance to ctx.req, is there anything special in it?:sparkles::seedling:Why not just pass locales data to the front end? Can you answer it for me, thank you~

While t is the main function to access all the translations - there are functions on i18n that you might need or not need (exist, dir, language, ... https://www.i18next.com/overview/api) -> does it hurt to pass it down - no...

But i think i18next is a litte too big.... Does its size affect the first screen rendering?

How should it...it's on the server it's in the request object and gets passed to your template handler or can be used for serverside rendering eg. a react tree -> it's not on the client...you don't res.send(i18n)

And i have an idea about if the amount of locale data is too large, we can get it asynchronously via i18next-xhr-backend. A webapp, for example, requires thousands of locale datas. Is my idea feasible?

jamuhl commented 4 years ago

that's what it does...you can structure your translations into multiple namespaces and load them on demand
