Project translated automatically. Log in or register, to view the original Prejudice: There is already a running application on Ionic Framework + Angular, but it works curved, the code is dirty, and the amateur interface.The application works online, sending requests to the server.About the application: the application was first made for the packaging of orders.We have a order with a list of goods, we open this order, and we pack the goods by clicking on them, or by scanning the barcode.When all the goods are processed, we close this order.Now you also need to add the application to the order creation function.In addition, there is a form of authorization, a product page, the ability to add the product, the barcode, the customer list, the user profile.Requirements: Write the same application in the style of Offline First App.Under the Offline First App there is no only to upload all data from the server and give the user the possibility to view them offline, but also the possibility to perform operations offline, and if there is a stable connection, synchronize them (or this operation must be initiated by the user).For example, the ability to add a customer, as well as the delivery address, well and create a order.Then send the data to the server.Until the data is sent, it should be possible to delete them, but you need to monitor the dependence, we cannot delete the customer if the order is linked to it.The submarine stones: I told you briefly, but there will be a lot of submarine stones ahead of you, as there will be no possibility to change the backdrop in a radical way.You have to work with what is.To update the data, in the presence of the internet, you probably would like to keep the socket connection to the server, but such a possibility will not be, you need to do either a polling or on the user's initiative to download the data.The second option is to imitate the work online, while if there is a good connection, then work online and send requests to the server, but if the connection is bad or off, continue to work offline.At the same time, even if there is a connection, requests for the type of input or data changes should be able to get in the order of requests, if the user is so convenient, rather than send directly to the server.The Stack: I think the best option is Ionic Framework.Angular/React/Vue to your choice.The preferences: I have the opportunity and desire to be in contact with you during the development of this application.I would like to have the opportunity to take part in the development, at least passive, to subordinate something, either to answer your questions, or to monitor the development process.I give preference to those for whom it is not a problem.This is also necessary because I don’t have a clear TZ in which everything is written, and every function will need to be discussed before the development, and during the development you will have 100% questions.We can agree on time.Because due to the lack of TZ it is difficult to assess the scale and cost of the project, the only right solution will be the hourly payment.You can write in your reply your reit.Leave your answers, I will contact you.
