Hi
美良 馮 •,
Welcome to Microsoft Q&A forum and thanks for using Azure Services.
As I understand, you want to know if you could use browser js access cosmosdb directly, without nodejs?
Refer to the official documentation which has details about different ways to connect to NOSQL Cosmos DB:
You may add your feedback over Azure Cosmos DB Feedback Channel https://feedback.azure.com/d365community/forum/3002b3be-0d25-ec11-b6e6-000d3a4f0858 so that team will consider this feature in the pipeline.
Hope this helps. Thank you.
