EcoShop is your innovative sustainability community, supporting the sale of preloved products and repair services using the latest Artificial Intelligence technologies, built on Huawei Cloud's amazing platform.
Thank you for checking out our GitHub Repository! Our frontend is built in React, and our backend is written in Python and NodeJS, powered by Huawei Cloud.
-
Bulk Listing - we allow users to upload one image containing multiple items, and automatically extract the items using Huawei Cloud Image Tagging to prepare multiple listings for users. This saves users' time and effort!
-
Natural Language Processing Chatbot Suggestions - powered by CTRLsum on Huawei Cloud ModelArts, our chat system scans seller-provided descriptions and buyer-sent questions to suggest the most suitable replies to the seller, reducing buyer waiting and effort required from sellers!
-
Video Platform - short-format videos have proven to be extremely effective in engaging users. Therefore, we incorporated a short-video oriented social media platform into EcoShop, allowing sellers to market their products better - especially for repair services! Powered by Huawei Cloud Media Processing Centre and Huawei Cloud Object Storage Service.
Our platform also incorporates other Huawei Cloud services to improve the user experience, allowing for automatic information extraction, fast, responsive APIs, and more!
Here is a brief summary of most of the Huawei Cloud Services we have used:
Contains most of our app data, as our app's use-case is well-suited to the relational database model. Indices are created for high performance querying.
Hosts our buyer-seller Websocket-based chat server, and an API that connects to Huawei Cloud Optical Character Recognition (OCR).
ModelArts hosts the CTRLsum Natural Langauge Processing API which powers many of our features, including chatbot suggestions and product attribute autofill.
We use Huawei Cloud OCR to identify and extract commonly-used product attributes from user-submitted images. This eliminates the need for users to copy information into product listings.
User-generated content such as videos and images is stored in OBS. Our static website is also hosted on OBS.
Furthermore, we use OBS' Image Processing Styles to save users' bandwidth and give users a better experience.
In order to support our engaging video platform, we used Huawei Cloud MPC to transcode user-uploaded videos to streaming formats (DASH + HLS) in a standardised resolution.
Huawei Cloud VPC is used to create a secure private network for our cloud resources (FunctionGraph functions, GaussDB for MySQL database, internal APIs) to communicate.
We used Huawei Cloud VPN and VPN Gateways to connect our VPC in Guangzhou to our VPC in Hong Kong, for some services such as GaussDB for MySQL.
Powers most of our app's API. We chose FunctionGraph as its serverless nature allows us to scale our services up and down according to user demand.
We use API Gateway to connect our FunctionGraph APIs to endpoints which can be accessed using standard HTTP.
Image Tagging is used to extract multiple items from one user-submitted image, powering our bulk listing feature.
Huawei Cloud Moderation keeps our platform safe from inappropriate content.
