    As far as I'm aware, PouchDB is pure JavaScript and doesn't have a REST API.

    Here's the discussion on failed attempts to integrate PouchDB into QML:

      I was referring to the Cloudant REST API

      I see. It's in a "maybe could work with some efforts but nobody's working on it" state.

        It seems to be like most of the large JavaScript frameworks: it assumes it's running in either a browser or node.js, and QML's JavaScript doesn't provide either of those environments.

          Yes.
          There's another non-JS (Android) adapter that's using the same tactics as the PyQt adapter (hidden Webview), but it's also unmaintained.
          What's strange is that IBM (Cloudant) is advertising PouchDB as the right solution for mobile apps sync, so they're focusing on "mobile" web apps maybe.

            Hi all,

            I think it would be helpful to create a Qt playground project so we could publish our backend wrappers in a commun repository. I have sent a request for creating the playground project to the development mailing list but I don't know whether it is the way to go...Do you know what is the process to follow to create a playground project ?

            So far, I have designed a QML plugin which is a work in progress :

            • the plugin only offers for now a Firebase backend element which is quite limited : the only supported authorization method is the secret token id and at this time it is only a thin wrapper around the REST API (GET, DELETE, POST, PATCH and PUT are supported).
            • what remains to be done :
              • define and implement an API suitable for supporting multiple backend : one option could be to design an API similar to the former enginio (create, update, query, uploadFile, downloadURL, remove...) but this API relies on backend features that we would have to mimics (users and usergroups, fileref...) so I am not sure this would be the way to go...
              • create a model that could be nicely used from QML like the former enginio model
              • use the Android and iOS sdk depending on the deployed platform (and using the REST sdk otherwise)
              • implement other backend using the same API (cloudant, apigee, BaaSBox...)

            I don't know if this does worth to publish this to github or to wait for the creation of a playground qt module...

              I'd say, if you have some code, even WIP, publish it. When discussing specs in a group, actual code can help to keep everyone on the same page.

              Given our limited resources, it would help a lot to have only a thin layer of code to add to another, wider audience project (at the moment Qt/QML on mobile is a small audience, sadly). I thinking specifically of Hood.ie. I don't know if it's technically feasible, but using Hoodie as a kind of middleware could save a lot of code; just mimicking its API could be useful too. Of course if (for instance) Hoodie is bound to the browser, we have the same problem as with PouchDB.

                I just finished a pure Qt Quick CouchDB interface (no C++ or plugins) which meets my current needs for storage. It would probably be trivial to get it work with Cloudant, but I'm not interested in adopting yet another BaaS provider that's going to disappear in a month or a year like Enginio and Parse did.

                  That's great! A CouchDB interface should be directly pluggable to the Cloudant service. See this. In fact, I gather that IBM is currently a main contributor to CouchDB, and was before the acquisition of Cloudant, which was originally an independant company. Think of Cloudant as CouchDB hosting + benefits.
                  The situation is different for Enginio because of the closed-source components. OTOH, CouchDB is an Apache project and Cloudant can be self-hosted if you don't like "public" clouds.

                  As an aside, why Enginio, or a least the main parts, can't be open-sourced is beyond me. Given the competitive nature of the Baas market, not having an "we-failed-commercially-but-here-is-the-source-code" exit plan is disappointing, given the Qt ties to the OSS/Free software world.

                      I've also looked at Apigee a while back and found the pricing plans a bit steep (starting at 300$/month without a datastore). Maybe I misunderstood that page ?

                        @gadlim You are right (sic) - Actually I missed that pricing page as I jumped directly to the console after having signed a trial free account. Apigee seems to match perfectly what I was looking for (100% RESTfull, push notifications, social login, already builtin collections for assets-users-group, console is complete and powerfull and documentation is comprehensive...). It is a very unclear what are the pricing plan for BaaS...but if it is really 300$/mo (or more) it will be a no go for me...

                        additional candidates :

                        • backend (https://www.backand.com/)
                        • app42 (http://api.shephertz.com/)

                          There's also Stamplay (https://stamplay.com/) that has some nice features, and others. The problem with these kind of vendors (Backendless, Stamplay, Backand, Firebase,...) is the lock-in. Like @xargs1, I'm wary of the future of the service, so I'm gravitating towards less black-boxy solutions, at least for the core DB services. For additional services like push, there's tons of options that can be plugged (and changed) separately if needed.
                          A tie-in to a particular technology (CouchDB or MongoDB for instance) is not ideal either, but it's a big plus if it's an OSS project IMO.

                            @gadlim I think the lock-in could be acceptable as long as we would use the backend services using a commun Qt API that would have a backup and reload function, don't you think ?
                            Regarding the push services, what would you advise as possible candidate ?
                            I have contacted Apigee to have a better understanding of their licence agreement, to summarize :

                            • the free trial period is supposed to be limited to 30 days but they usually don't stop the trial period after 30 days
                            • they do not propose a package containing only BaaS, so to get BaaS you need the enterprise-class Edge account which licence fee is around 200k$ yearly (!!!)...

                            FYI here is the transcript of the chat conversation :

                            guillaume: at 16:23:33
                            Hi, I am an independant mobile application developper looking for a backend solution in
                            replacement of engin.io cloud services (I am using Qt framework). I am evaluating apigee BaaS
                            which I find great but I am confused with the pricing...
                            guillaume: at 16:24:45
                            In the pricing table, the BaaS is checked only for the trial column. what happens after the 30 days
                            trial period ?
                            Dylan: at 16:24:51
                            Well BaaS is only available with our enterprise solution
                            Dylan: at 16:25:11
                            You can download the free trial and use as you please
                            Dylan: at 16:25:33
                            We are usually not to strict on ending people's trials at the 30 day mark
                            guillaume: at 16:27:26
                            Does that mean that I can continue using BaaS for unlimited period as long as I use the API within
                            the maximal API calls ?
                            Dylan: at 16:28:35
                            I wouldn't say unlimited but you can continue to use it and if you have any issues please reach out
                            to us
                            guillaume: at 16:29:44
                            What would be the price for using BaaS only ?
                            Dylan: at 16:30:38
                            You have to have our enterprise Edge version to use Apigee BaaS
                            guillaume: at 16:31:51
                            I haven't found the price of edge version, and I think that this package contains much more than
                            my current needs.
                            Dylan: at 16:32:02
                            We have Start Up and SMB Edge versions as well but they do not come with BaaS
                            Dylan: at 16:33:27
                            Enterprise Edge starts at 200K a year is that within your budget? If not, you are not going to be
                            able to use a paid version of Apigee BaaS.
                            guillaume: at 16:35:20
                            It is definitely not within my budget unfortunately...do you plan to propose a package for indie
                            (with BaaS only) that I could propose to my customer in addition with the mobile development ?
                            guillaume: at 16:37:19
                            My typical use case would be to develop a mobile application using apigee for a customer and to
                            sell the product. The customer would have to pay for Apigee services fee (+variable cost
                            depending of API usage)
                            guillaume: at 16:37:55
                            Is this kind of package offering already in your roadmap ?

                            guillaume: at 16:42:27
                            If I have to invest time on Apigee I would need to ensure the business model is relevant for my
                            customers...
                            Dylan: at 16:44:34
                            Well if you need Apigee BaaS and you don't have a six figure budget then this platform is most
                            likely not going to suit your needs. If Apigee BaaS is a nice to have and you are interested in our
                            SMB or Start Up API Management solutions then I suggest attending a session.

                            think most of my customers could afford to pay a couple of hundred dollars of reccurent fee for
                            the backend services

                            Okay, we do have authentification and push notifications.

                            will that mean that my in my typical use case, let's say a company order a small application using
                            datastore, push notification, and authentification...It would cost let's say 5k$ for my development
                            but the customer would have to get a edge account (200k$ yearly) to continue using the app ?
                            Dylan: at 16:50:29
                            The Edge package that they need depends on their API call volume

                            but they would need a Edge account (enterprise account) which you told me is around 200k$
                            yearly
                            Dylan: at 16:52:22
                            No, they only need an enterprise level account if they want BaaS
                            Dylan: at 16:52:42
                            BaaS is not available on the SMB or Start Up level subscriptions
                            Dylan: at 16:53:04
                            Without BaaS they could definitely choose one of the cheaper versions
                            guillaume: at 16:55:42
                            My understanding is that you are currently not proposing a BaaS only package (much cheaper
                            than edge) for mobile application...do you think this could be proposed in a near future ?
                            Dylan: at 16:56:29
                            I am not sure if we will offer that but yes we do not have a standalone BaaS offering at the
                            moment
                            guillaume: at 16:56:59

                              To help synthesize the results of our evaluation of the different BaaS services, I propose to work on a commun document where we could all insert/edit the solutions we know (and also correct each other).

                                @gadlim I think the lock-in could be acceptable as long as we would use the backend services using a commun Qt API that would have a backup and reload function, don't you think ?
                                Regarding the push services, what would you advise as possible candidate ?
                                I have contacted Apigee to have a better understanding of their licence agreement, to summarize :

                                • the free trial period is supposed to be limited to 30 days but they usually don't stop the trial period after 30 days
                                • they do not propose a package containing only BaaS, so to get BaaS you need the enterprise-class Edge account which licence fee is around 200k$ yearly (!!!)...

                                FYI here is the transcript of the chat conversation :

                                guillaume: at 16:23:33
                                Hi, I am an independant mobile application developper looking for a backend solution in
                                replacement of engin.io cloud services (I am using Qt framework). I am evaluating apigee BaaS
                                which I find great but I am confused with the pricing...
                                guillaume: at 16:24:45
                                In the pricing table, the BaaS is checked only for the trial column. what happens after the 30 days
                                trial period ?
                                Dylan: at 16:24:51
                                Well BaaS is only available with our enterprise solution
                                Dylan: at 16:25:11
                                You can download the free trial and use as you please
                                Dylan: at 16:25:33
                                We are usually not to strict on ending people's trials at the 30 day mark
                                guillaume: at 16:27:26
                                Does that mean that I can continue using BaaS for unlimited period as long as I use the API within
                                the maximal API calls ?
                                Dylan: at 16:28:35
                                I wouldn't say unlimited but you can continue to use it and if you have any issues please reach out
                                to us
                                guillaume: at 16:29:44
                                What would be the price for using BaaS only ?
                                Dylan: at 16:30:38
                                You have to have our enterprise Edge version to use Apigee BaaS
                                guillaume: at 16:31:51
                                I haven't found the price of edge version, and I think that this package contains much more than
                                my current needs.
                                Dylan: at 16:32:02
                                We have Start Up and SMB Edge versions as well but they do not come with BaaS
                                Dylan: at 16:33:27
                                Enterprise Edge starts at 200K a year is that within your budget? If not, you are not going to be
                                able to use a paid version of Apigee BaaS.
                                guillaume: at 16:35:20
                                It is definitely not within my budget unfortunately...do you plan to propose a package for indie
                                (with BaaS only) that I could propose to my customer in addition with the mobile development ?
                                guillaume: at 16:37:19
                                My typical use case would be to develop a mobile application using apigee for a customer and to
                                sell the product. The customer would have to pay for Apigee services fee (+variable cost
                                depending of API usage)
                                guillaume: at 16:37:55
                                Is this kind of package offering already in your roadmap ?

                                guillaume: at 16:42:27
                                If I have to invest time on Apigee I would need to ensure the business model is relevant for my
                                customers...
                                Dylan: at 16:44:34
                                Well if you need Apigee BaaS and you don't have a six figure budget then this platform is most
                                likely not going to suit your needs. If Apigee BaaS is a nice to have and you are interested in our
                                SMB or Start Up API Management solutions then I suggest attending a session.

                                Yes, but a real, production-ready, common Qt API is a hard task. We're not there yet.

                                Regarding the push services, what would you advise as possible candidate ?

                                I haven't used any (using Pushbullet but that's different), so can't really advise.

                                      Follow-up on my Cloudant evaluation: I ran into problems trying to figure out how to encrypt user passwords.
                                      I'll have a conversation on that subject with IBMers tomorrow.
                                      I hope to also discuss the broader subject of whether Cloudant is a good fit for 2-tiers apps (no server code, or almost no server code).

                                      If you guys have questions, tell me, I'll try to insert them in the conversation.

                                      Follow-up to the follow-up:

                                      • user passwords have to be manually-encoded (not a big deal but annoying)
                                      • 2-tiers apps; not a perfect fit, for the above reason and others

                                      Coming from Enginio (MongoDB), the migration can be painful. The main problem is that it's not as much "forget-there's-even-a-database" as MongoDB is. For instance you don't have the concept of the collection, so if you treat each collection as a separate DB in CouchDB, you have to manage different DBs, and for each DB you have to think ahead about the indexes you need (in MongoDB indexes are are not mandatory for queries).
                                      In contrast, the Parse REST API is eerily similar to the Enginio API. There's not so many ways to implement a REST API over MongoDB, but still you have to wonder if Enginio used Parse.com as an inspiration.

                                      In my case, I'm running out of time and have a fair amount of code to port, so my choice is made: I'll go with a Parse Server hosting. There's several options, I think I'll go with IBM Bluemix. I've followed the instructions to setup a Parse server, it involved a whole day of trial-and-error but it's working, and I've ported our main app in less than a day - it's just a matter of tweaking some parameters. It's not fully working yet because of the fact that Parse only sends back the ID of new objects instead of the whole objects, but it's still ten times easier than other options.

                                      Porting the Enginio SDK to Parse Server or anything similar should be easy too.

                                        @gadlim regarding the user passwords, If I am correct, there are 2 different methods, one can either base64 encode username:password to be passed as header (with "Basic " as a prefix) or you can post with something like this :

                                        QUrlQuery postData;
                                        postData.addQueryItem("name", user);
                                        postData.addQueryItem("password", password);
                                        QNetworkAccessManager NAM;
                                        NAM.post(request, postData.toString(QUrl::FullyEncoded).toUtf8());
                                        

                                        I don't really understand the 2-tiers issue as you can directly use Cloudant i.o Cloudant through BlueMix, what would be your concern in this case ?

                                        I have spend the last days playing with BlueMix (as I need to set up Push Notification) but regarding Cloudant I came to same conclusions that this lack of collection principle might be an issue for porting enginio apps...Firebase seems to be a much better candidate in this field (and Firebase has a powerfull mecanism to notify asynchronously when new data comes in - in replacement of enginion web socket - and I haven't found something similar with Cloudant...that would be another issue when polling is not an option).

                                        I am very interested in the Parse Server hosting solution...I thought Parse was a no go as they are ramping down the services this year...do FB plans to release Parse to opensource (or did they already do ?). BTW, do you know what are their reasons for stopping the service ?
                                        -Edit - replying to myself ;-) - Parse.com did release to opensource the datastore which is great - but the not the complete Parse solution (social login, PN, auth...), anyhow Parse server is promising ! I think I will have a try...

                                          I'm refering to the way the password is stored in the DB, not how it's sent to the server. In Enginio it's hidden (and probably encrypted), in Parse it's encrypted, etc. For Cloudant you have to encrypt yourself in the client or in an "update function" you're setting on the server.

                                          I don't really understand the 2-tiers issue as you can directly use Cloudant i.o Cloudant through BlueMix, what would be your concern in this case ?

                                          Nothing in particular, except passwords, but there's a feeling you get from the sample apps + the opinion from others that used it that you're expected to write some server code for "serious" applications.

                                          I have spend the last days playing with BlueMix (as I need to set up Push Notification) but regarding Cloudant I came to same conclusions that this lack of collection principle might be an issue for porting enginio apps...Firebase seems to be a much better candidate in this field (and Firebase has a powerfull mecanism to notify asynchronously when new data comes in - in replacement of enginion web socket - and I haven't found something similar with Cloudant...that would be another issue when polling is not an option).

                                          Maybe PouchDB can manage async data updates through the offline / online mechanism, but I haven't explored it.

                                          It's too early to know how the OSS Parse project will evolve, but it starts with a good momentum (around 600 000 apps), so it think it should carry on. For now, missing services are provided by the hosters, but for instance Push notifications have already been added.

                                          What's interesting about Bluemix is that they have everything. But that's also a problem if you don't have a guide, because you're quickly lost in a sea of various tools and services. See for instance this , and that's just one single service.
