I have very simple project in angular 4, where i need to integrate chat api inside it. My first preference is [login to view URL] . You can look at documentation here [login to view URL] I am myself a programmer (beginner though), so you can either work as consultant or you can do it yourself. I am open to both the proposals. But, in both the scenerios, i will like to learn myself how to integrate chat api inside angular project. The codebase is extremely simple. Its just a basic angular project, something which you can expect from students. So, there is virtually no existing code to go through. If you know how to integrate chat api, you will breeze through it. I am myself more interested in hiring consultant on hourly basis. Because we will need more help in future. So, there wont be any strict deadlines , you can work anytime you like. But i hope that helps me in keeping the cost low. So, please mention in bid you will like to build it yourself or you are interested in consulting position. Tthis is the project, i am working , very simple very basic trying to learn MEAN stack [login to view URL] If we decide hourly rate than i can open another project as well. Just keep in mind that I am student and I am looking for affordable rate.
