The Web-based remote participation system for experimental advanced superconducting tokamak (EAST RPS) has been developed to provide a high-efficient and low-cost way to meet international collaboration requirements. The EAST RPS team focused on the extension, update, and optimization for the RPS during last two years. In the first version, EAST RPS has established Apache-Flex based front-end components to provide a platform-independent user interface. However, some Web browsers, such as Firefox, Google Chrome, and Microsoft Edge, and operation systems (iOS and android) stop supporting or disable the flash player plugin by default, and the Flex technology will become less relevant in the future. The purpose of this paper is to provide an update of the RPD in EAST. The front-end migration should be a priority to update the EAST RPS. The open source, cross-platform, maintainability, and life cycle are the key features that the front-end platform must have. The technical solutions for the new user front end for EAST RPS are offered in this paper.
