Abstract: Taking the open source software project AngularJS as an examplethis paper studies the key developer type and the robustness of collaboration network in open source software.The network is constructed by the project code-collaboration relationships to analyze the structure and function.The nodes in the network are classified into different types according to their structure features and function features.Thenthe impact of different developers turnover on the network structure and functional robustness is explored to identify the key developer type.What's morethe promotion strategy on robustness of the network is promoted by simulating the joining mechanism for new developers.The study shows that the developer's structure and function features are asymmetricalwhich is the reason for the structure and function robustness on the network are inconsistent.Compared with traditional methodsthe type division of developers can more effectively identify the key developer type.Central core deve-lopers who are active in the community and have connections with other communities also have a large number of contributionsand this type of developers have the greatest impact on the robustness of the network.New developers with higher initial degree and choosing a preference connection mechanism can effectively improve the robustness of collaboration network.

Key words: AngularJS, Developer collaboration network, Key developer type, Open source software, Robustness
