Building my first module, using MMM-API

As I read the document of MMM-API, ACTION would be the name of notification of target module. (It’s obvious whether notification could be case-insensitive.)
By example,
MMM-Glance module works with notification GLANCE_ON, Thus MMM-API doc says

curl -X POST 'http://localhost:3001/api/v1/modules/mmm-glance/glance_on?name=news&time=1000'

will activate MMM-Glance. This curl execution will be equivalent with the notification GLANCE_ON with payload value {name:"news", time:1000}.

@sean Got it! Thanks

@Sean Did some progress on the module. I removed the dependency on MMM-API since we can define extra routes in node_helper.js.

Now i have a doubt. Should i keep the values that i wish to retrieve in a variable and use the socketNotificationSend/socketNotificationReceived logic or… should i call the extra-routes from my module (MMM-PiggyBank.js) pretending that i’m accessing an external API?

Could you kindly tell me which is the recommended approach?

extraRoutes: function() {
                var self = this;
                this.expressApp.get("/MMM-PiggyBank/WITHDRAW", function(req, res) {
                        self.withdrawCash().then((rsp) => res.status(rsp.status).send(rsp.response));
                });
                this.expressApp.post("/MMM-PiggyBank/CASH_IN", function(req, res) {
                        self.updateCash(req.query.target,req.query.current).then((rsp) => res.status(rsp.status).send(rsp.response));
                });
        },

       updateCash: async function(target,current) {
                var self = this;
                try {
                        await self.checkExistance(self.fullyQualFileName());
                        var oldcontent = await readFile(self.fullyQualFileName());
                        var contentcandidate = await self.valChanges(target, current, JSON.parse(oldcontent));
                        var newcontent = await writeFile(self.fullyQualFileName(), JSON.stringify(contentcandidate));
                        return self.buildSuccessRsp("Successfully saved!");
                }
                catch(err) {
                        return self.buildErrRsp(err);
                }
        },

        withdrawCash: async function() {
                var self = this;
                try {
                        await self.checkExistance(self.fullyQualFileName());
                        var oldcontent = await readFile(self.fullyQualFileName());
                        return self.buildSuccessRsp(JSON.parse(oldcontent));
                }
                catch(err) {
                        return self.buildErrRsp(err);
                }
        },

I think, there might be no silver bullet or Deus Ex Machina about that kinds of question. I believe anything be good if you can handle it.

Finally finished my first module.
Nothing too fancy but fits my requirements.
