    (Review updated until commit https://github.com/Hu-Fi/Mr.Market/commit/6b7a33dae357b80a4e01cb73af51db8d60dc7ad7)

    โฑ๏ธ Estimated effort to review [1-5] 4
    ๐Ÿงช Relevant tests Yes
    ๐Ÿ”’ Security concerns - Sensitive Information Exposure:
    Storing JWT tokens in the database as plain text in `mixin-user.entity.ts` can expose sensitive information if the database access is compromised.
    โšก Key issues to review Possible Bug:
    The error handling in the getOauth function in auth.ts does not specify what happens after logging the error. It should ideally handle the error gracefully or propagate it to the caller.
    Security Concern:
    Storing JWT tokens in the database without any form of encryption or hashing could lead to security vulnerabilities if the database is compromised.
    Code Quality:
    The mixinAuthWrapper function in mixin.ts has a complex flow with nested conditions and callbacks, which could be simplified for better maintainability.
    Redundancy:
    The authorize function's URL handling in mixin-oauth.ts seems redundant as it constructs a URL that is never altered or conditionally changed.

    Enhancement
    Correct a typo in the environment variable name for clarity and consistency ___ **Correct the typo in the environment variable name from RUN_STARTEGY_FOR_MIXIN_ORDERS to
    RUN_STRATEGY_FOR_MIXIN_ORDERS to ensure consistency and avoid potential misconfigurations
    due to spelling errors.** [server/.env.example [38]](https://github.com/Hu-Fi/Mr.Market/pull/196/files#diff-fc96f2f1bbacb040ddac600e209d0de9ce16d436be88d3995e3f72f159adc21bR38-R38) ```diff -RUN_STARTEGY_FOR_MIXIN_ORDERS= +RUN_STRATEGY_FOR_MIXIN_ORDERS= ```

    user feedback.** [interface/src/lib/helpers/hufi/auth.ts [12]](https://github.com/Hu-Fi/Mr.Market/pull/196/files#diff-75bfdc281703d0fd42b0947595aef50bd80a5d1dc74fd56ac76b5ef4aa8ec00eR12-R12) ```diff -console.error('Error fetching orders by user:', error); +console.error('Error in OAuth token fetching:', error); ```
    Suggestion importance[1-10]: 7 Why: Improving the specificity of error messages enhances debugging and user feedback, although it is not critical for functionality.
    7
    Robustness
    Add error handling for the authentication process to improve robustness ___ **Ensure that the mixinAuthWrapper function properly handles both success and error
    scenarios by implementing error handling within the function or in the calling context to
    improve the robustness of the authentication process.** [interface/src/lib/components/common/connectWalletBtn.svelte [13]](https://github.com/Hu-Fi/Mr.Market/pull/196/files#diff-e4c4aabcf6a4083502cddfbd41e4ba22bff0ecf35ece70283f5c287ad7ed8b78R13-R13) ```diff -await mixinAuthWrapper(false); +try { + await mixinAuthWrapper(false); +} catch (error) { + console.error('Authentication failed:', error); +} ```

    8
    Maintainability
    Encapsulate password hashing in a utility function for better maintainability ___ **Replace the direct usage of CryptoJS.SHA3 with a dedicated utility function for password
    hashing. This encapsulates the hashing logic, making the code cleaner and more
    maintainable. It also allows easy updates to the hashing mechanism in one place without
    modifying the component code.** [interface/src/lib/components/admin/login.svelte [13]](https://github.com/Hu-Fi/Mr.Market/pull/196/files#diff-7755e80262efe6164fbaf4735da93fec7a0be5fa871982016ef1dbac24d493fcR13-R13) ```diff -const hashedAdminPassword = CryptoJS.SHA3(pass, { outputLength: 256 }).toString(CryptoJS.enc.Hex); +const hashedAdminPassword = hashPassword(pass); ```

    Error handling
    Add error handling for login attempts to improve user feedback and error management ___ **Add error handling for the checkPassword function to manage failed login attempts
    gracefully.** [interface/src/lib/components/admin/login.svelte [15-18]](https://github.com/Hu-Fi/Mr.Market/pull/196/files#diff-7755e80262efe6164fbaf4735da93fec7a0be5fa871982016ef1dbac24d493fcR15-R18) ```diff -const accessToken = await checkPassword(hashedAdminPassword); -if (accessToken) { - submitted.set(true); - checked.set(true); +try { + const accessToken = await checkPassword(hashedAdminPassword); + if (accessToken) { + submitted.set(true); + checked.set(true); + } else { + throw new Error('Invalid password'); + } +} catch (error) { + console.error('Login failed:', error); +} ```

    more descriptive and includes the error type. This can help in debugging by providing more
    context about the error.** [interface/src/lib/helpers/hufi/auth.ts [12-13]](https://github.com/Hu-Fi/Mr.Market/pull/196/files#diff-75bfdc281703d0fd42b0947595aef50bd80a5d1dc74fd56ac76b5ef4aa8ec00eR12-R13) ```diff } catch (error) { - console.error('Error fetching orders by user:', error); + console.error(`Error in getOauth: ${error instanceof Error ? error.message : error}`); } ```
    Suggestion importance[1-10]: 7 Why: Improving error logging to include specific error messages enhances debugging and provides more context, which is beneficial for maintenance.
    7
    Enhance error handling in the authentication wrapper to improve user feedback ___ **Refactor the mixinAuthWrapper function to handle errors more gracefully by not only
    logging them but also potentially notifying the user interface or retrying the operation,
    depending on the application's requirements.** [interface/src/lib/helpers/mixin.ts [234-238]](https://github.com/Hu-Fi/Mr.Market/pull/196/files#diff-acf423272bdc878982f8a993563883c5ac16fcef547cb0e7a09972c785a5e839R234-R238) ```diff onError: (error: Error) => { - console.error(error); + console.error('Authentication error:', error.message); + alert('Authentication failed, please try again.'); mixinConnectLoading.set(false); - return; }, ```

    6
    Maintainability
    Refactor the user token update logic to separate concerns and simplify the method ___ **Refactor the checkAndUpdateUserToken method to separate concerns for checking user
    existence and updating user details.** [server/src/modules/mixin/user/user.service.ts [103-107]](https://github.com/Hu-Fi/Mr.Market/pull/196/files#diff-537368cd1f4b8ed89954ffec0e9dc97d2c9fd6a338dcf9d1dd18d81152a0a536R103-R107) ```diff const userExists = await this.checkUserExist(user_id); -if (userExists) { - await this.updateUserToken(user_id, jwt_token); -} else { - await this.addUser(mappedUser); -} +const action = userExists ? this.updateUserToken(user_id, jwt_token) : this.addUser(mappedUser); +await action; ```
