jest.config.ts (4)
1-2: Imports are appropriate.The import statements for
ConfigandnextJestare necessary for setting up Jest configuration for a Next.js application.
4-7: Jest configuration creation looks good.The
createJestConfigfunction is correctly set up to load the Next.js configuration and environment variables from the root directory.
10-18: Custom Jest configuration is comprehensive.The custom configuration includes:
coverageProvider: Set to "v8" for code coverage.testEnvironment: Set to "jsdom" for simulating a browser environment.testMatch: Patterns for matching test files.setupFilesAfterEnv: Specifies the setup file for custom matchers.moduleNameMapper: Maps module paths for easier imports.These settings are appropriate for testing a Next.js application.
20-21: Jest configuration export is correct.The Jest configuration is exported using
createJestConfig, ensuring that the Next.js configuration is loaded asynchronously.package.json (3)
19-20: New test scripts are appropriate.The new scripts for testing are:
"test": "jest --watch": For interactive testing."test:ci": "jest --ci": For continuous integration testing.These scripts enhance the testing capabilities of the project.
54-75: New devDependencies are essential.The new devDependencies for testing include:
@testing-library/jest-dom@testing-library/react@types/jestjestjest-environment-jsdomts-nodeThese dependencies are essential for setting up a comprehensive testing framework for the project.
2-83: Overall changes inpackage.jsonenhance testing capabilities.The changes in
package.jsoninclude new scripts and devDependencies that significantly enhance the project's testing capabilities, aligning with the goal of introducing Jest and improving the testing framework.

19-20: LGTM: Test scripts added for development and CI environments.The addition of
testandtest:ciscripts introduces Jest for running tests, which is a great improvement to the project's testing capabilities. The--watchflag for development and--ciflag for CI environments are appropriate choices.Consider adding a
test:coveragescript to generate test coverage reports:"test": "jest --watch", "test:ci": "jest --ci" + "test:coverage": "jest --coverage"This will help track the project's test coverage over time.

154-171: Add error handling for thefetchoperationThe
fetchrequest lacks error handling. If the network request fails or the response is invalid, it could lead to unhandled promise rejections and runtime errors. Consider adding a.catch()block to handle errors gracefully.Apply this diff to add error handling:
fetch(PROMPT_URL) .then((res) => res.json()) .then((res) => { // existing code }) + .catch((error) => { + console.error('Error fetching prompts:', error); + // Optionally, handle the error (e.g., set default prompts or notify the user) + });
Line range hint
158-160: Handle potential undefined prompt dataThe code assumes that
res.en,res.tw, andres.cnexist in the fetched data. If any of these properties are missing or undefined, it could cause runtime errors. Consider providing default empty arrays to ensure robustness.Apply this diff to provide default values:
let fetchPrompts = [ - res.en, - res.tw, - res.cn + res.en || [], + res.tw || [], + res.cn || [] ];
Line range hint
165-166: Simplify array flattening usingflat()You can simplify the flattening of
builtinPromptsby using theflat()method instead ofreduceandconcat, improving readability.Apply this diff to simplify the code:
const allPromptsForSearch = builtinPrompts - .reduce((pre, cur) => pre.concat(cur), []) + .flat() .filter((v) => !!v.title && !!v.content);Note: Ensure that the environment supports
Array.prototype.flat(), available in ES2019 and later.
Line range hint
159-161: Enhance language handling for future scalabilityThe current logic reverses
fetchPromptswhen the language iscn. To support additional languages in the future, consider refactoring this logic to be more dynamic.For example, you could map language codes to prompt data in an object:
- let fetchPrompts = [res.en, res.tw, res.cn]; - if (getLang() === "cn") { - fetchPrompts = fetchPrompts.reverse(); - } + const languageOrder = { + en: [res.en, res.tw, res.cn], + cn: [res.cn, res.tw, res.en], + }; + const currentLang = getLang(); + let fetchPrompts = languageOrder[currentLang] || [res.en, res.tw, res.cn];This approach allows for easy extension to other languages and custom ordering.
Line range hint
154-171: Consider usingasync/awaitfor better readabilityRefactoring the promise chain with
async/awaitcan improve code readability and simplify error handling. Ensure thatonRehydrateStoragesupports asynchronous functions before making this change.If supported, apply this diff:
+ onRehydrateStorage: async (state) => { // Existing code if (typeof window === "undefined") { return; } const PROMPT_URL = "./prompts.json"; type PromptList = Array<[string, string]>; - fetch(PROMPT_URL) - .then((res) => res.json()) - .then((res) => { + try { + const response = await fetch(PROMPT_URL); + const res = await response.json(); // existing code within the .then blocks + } catch (error) { + console.error('Error fetching prompts:', error); + // Handle error accordingly + } },Note: Verify that
onRehydrateStoragecan handle asynchronous operations without affecting the store rehydration process.

package.json (5)
9-9: LGTM: Running tests before build is a good practice.Adding
yarn test:cito the build script ensures that tests are run in a CI environment before building the application. This change helps catch potential issues early in the development process.
12-12: LGTM: Consistent approach for running tests before export.Adding
yarn test:cito the export script maintains consistency with the build script and ensures that tests are run before exporting the application. This change contributes to a more robust development workflow.
15-15: LGTM: Consistent approach for running tests before Tauri app build.Adding
yarn test:cito the app:build script maintains consistency with the build and export scripts. This ensures that tests are run before building the application using Tauri, contributing to a more robust development process.
Line range hint
1-89: Overall LGTM: Testing setup enhanced, minor verification needed.The changes to package.json significantly improve the project's testing capabilities by introducing Jest and related dependencies. The modifications to build scripts ensure tests are run before building or exporting the application, which is a good practice for catching issues early.
Regarding the past comment about formatting:
lloydzhou: 这里怎么把package.json完全格式化了？？？(Translation: "Why is package.json completely formatted here???")
The current diff doesn't show significant formatting changes. It's possible that the formatting was addressed in a previous commit or that the changes appear more substantial due to the diff representation.
To ensure all changes are intentional, please run the following command and verify that only the expected changes are present:
#!/bin/bash # Show a condensed diff of package.json git diff --color-words package.json | grep -v '^\+\+\+\|^---\|^index\|^diff'This will help confirm that no unintended formatting changes were introduced.
59-61: LGTM: Testing dependencies added, but please verify one version.The addition of testing-related dependencies (@testing-library/jest-dom, @testing-library/react, @types/jest, jest, jest-environment-jsdom, ts-node) is consistent with the introduction of Jest for testing and enhances the project's testing capabilities.
However, please verify the version of @testing-library/react:
The current version (^16.0.0) seems unusually high and might be incorrect. The latest version as of my last update was in the 13.x range. Please double-check and update if necessary.
Also applies to: 77-78, 81-81
