Abstract The stable collaboration relationship between developers in open source software community can promote the emergence of community collective innovation. Taking the open source software project AngularJS as an example to study the impact of the stability on developer collaboration network in open source software community, which was caused by staff turnover. We construct the network by the project code-collaboration relationships. Then we analyze the structure and function of the developer collaboration network. According to the structure features and function features of the nodes, we classify them into different types, then explore the impact of the loss of different types of nodes on the network structure and functional stability. The study found that the developer's features are asymmetrical, which is the reason of the structure and function stability on the network are inconsistent; Different types of developers have different influences on network stability. A member owes large degree may not be the most important in the network; Coordination center developers who with high within-module degree and participation coefficient also have large knowledge contributions; Developers participating in multiple subprojects often occupy the center of the network. These two types of developers have a greater impact on network stability.
