Discussion

Points to discuss [from Arpit]

• Playground mono
• Let’s use the word DiceDB and not Dice, every where, there are variable and config places where the word Dice is used
• The config “REQUEST_LIMIT” should be “REQUEST_LIMIT_PER_MIN”
• The config “REQUEST_WINDOW” should be “REQUEST_WINDOW_SEC”
• What is the purpose of the package internals/cmds?
• Why is there a package called db that just is a wrapper over DiceDB commands? Supporting a new command in Playground now means making a change in both backend and frontend. Also, these functions are essentially useless now.
• Also, A better way would be for SDK to expose a generic command that takes command and argos and executes the. What do you think?
• With this, the need for diced.go vanishes
• Instead of exposing the endpoint as `/cli`, let’s call it `/shell/exec`
• We need all errors to be standardized w.r.t casing. I propose everything to be lowercase.
• server/httpServer.go -> server/http.go, why again the word “server”
• “errorResponse” function should do JSON marshal and not string format
• I see places where log and slog both being used, let’s just use slog everywhere
• Need to understand pkg/util/helpers.go, neither the name not the function made much sense.
• Playground Web
• Have a .env file that can take playground mono URL which points to API URL
• Do not call it `CLI_COMMAND_URL`, a bad name. Call it `PLAYGROUND_MONO_URL`
• Should we not check in package-lock.json? When I installed the file, it got modified
• README lacks node version requirement
• Does this output static site or does it require a server to run? I see the command `npm run start` to start the server in production. Ideally, we want a static website for the playground web. No servers.
• Why is Dockerfile_Backend file even present in web? Also, very bad name. We are calling it Playground Mono. Also, the name is neither snake nor camel case.
• “CLI” is a bad name, let’s call it Shell.
• “ // comment this to hide footer” is such a useless comment.
• Comments are supposed to be `// comment` and not `//comment`
• “DiceDB PlayGround” as name should be “DiceDB Logo” “Playground”
• “Cleanup in :” and “Command left:” have inconsistent styling. Also, it should be `Commands left`. Add a tool tip (i) button, next to both that tells what these limits are all about.
• Move commands from command.ts file to using DiceDB commands command
• Delete mock data file
• In api.ts, propagate the error to the use instead of just logging it to console. Show user the error that was emitted from the backend/mono.
• Constants file may not be required rightnow, given we should use Playground Mono URL from .env
• Instead of calling “blacklist” let’s use the word “blocklist”
• Why cliUtils has get and set and delete, do we not support any other command? Also, given this file is present in utils folder it should be called `utils/cli.ts` and not `utils/cliUtils.ts`
