I'm new to Node/Express.. I see GET params can be captured like so:

app.get('/log/:name', api.logfunc);

POST like so:

app.post('/log', ... (form variables available in req.body.)

I'm aware of app.all, but is there a single way I can get all the variables for GET and POST when using app.all? (I'm too used to $_REQUEST in php!:)

thx,

express node.js javascript

Personnaly, i merge req.params, req.body, req.query in one single object req.props with Object.assign()

in ES6:

You just need to write this in your route:

   app.all('/myroute/:myparam', (req, res, next) => {
        // merge all req data in one
        req.props = Object.assign(req.query, req.params, req.body);
        // optional :
        // delete req.query;
        // delete req.params;
        // delete req.body;
    });

In ES5:

    app.all('/myroute/:myparam', function(req, res, next){
        // merge all req data in one
        req.props = {};
        if(req.query)  for (var attrname in req.query)  { req.props[attrname] = req.query[attrname]; }
        if(req.params) for (var attrname in req.params) { req.props[attrname] = req.params[attrname]; }
        if(req.body)   for (var attrname in req.body)   { req.props[attrname] = req.body[attrname]; }
        // optional :
        // delete req.query;
        // delete req.params;
        // delete req.body;
    });

Now, you can access easily to your GET, POST, PUT params with req.props in all your routes, be careful about similars name if you decide to delete the old req.

Also, you can do a middleware/functions to make it more useful yet.
