 ## Notes
 
-- after installing libraries, update `node_modules/tc-core-library-js/lib/auth/verifier.js`, at line #23, add code:
-  `return decodedToken && decodedToken.payload ? callback(null, decodedToken.payload) : callback(new Error('invalid token'));`,
-  so that we will ignore the JWT verification, and directly use the decoded payload;
-  this is because we don't know the JWT auth secret to verify the TC auth token.
-  In production, if we properly configure AUTH_SECRET and VALID_ISSUERS, then we don't need this code change.
-
-- I tried to fix some vulnerabilities issues, but not all are fixed, because many are due to ui's old libraries,
-  and upgrading them will incur much code changes, so I don't fix them to avoid code change risks
-
-- API security is handled at `src/app.js`
-
-- web socket security is handled at `src/dataStreamWS.js`, see `authorized` related handling
-
-- tests are improved at `test/datastream.test.js`
-
-- front end is updated to send token to back end API and web socket
