Error connecting to Azure: Illegal character in password with mongoose 5.0.1 but works in 4.13.9

Question

I have a node.js application that is deployed to azure using CosmosDB and the MongoDB API. My application uses mongoose which works seamlessly in 4.13.9.

Answer 1

To connect to local cosmos db emulator use the following connection method (for mongoose > 5.0.0):

  mongoose.connect(

  `mongodb://localhost:10255/?ssl=true`,
  {
    auth: {
      user: "localhost",
      password: "C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw==",
      dbName: "admin"
    }
  }
);

Or you may also do the following:

const encodedPassword = encodeURIComponent("C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw==");
mongoose.connect(`mongodb://localhost:${encodedPassword}@localhost:10255/admin?ssl=true`);

Connection string has following format:

mongodb://username:password@host:port/[database]?ssl=true

and there seems to be some issue with default password character escaping. Thus we encoded it separately.
