TS-Jest不解析tsconfig路径

Question

我已经将这些路径添加到tsconfig.json

{
    "compilerOptions": {
        "lib": ["ESNext"],
        "moduleResolution": "node",
        "noUnusedLocals": true,
        "noUnusedParameters": true,
        "removeComments": true,
        "sourceMap": true,
        "target": "ES2020",
        "outDir": "lib",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "baseUrl": ".",
        "paths": {
            "@lambdas/*": ["src/lambdas/*"],
            "@services/*": ["src/services/*"],
            "@types/*": ["src/@types/*"],
            "@configs/*": ["src/configs/*"],
            "@database/*": ["src/database/*"],
            "@entities/*": ["src/entities/*"],
            "@validations/*": ["src/validations/*"],
            "#serverless/*": ["serverless/*"]
        }
    },
    "include": ["src/**/*.ts", "serverless.ts"],
    "exclude": [
        "node_modules/**/*",
        ".serverless/**/*",
        ".webpack/**/*",
        "_warmup/**/*",
        ".vscode/**/*"
    ]
}

在jest.config.js中，我添加了以下内容：

const { pathsToModuleNameMapper } = require('ts-jest/utils');
// eslint-disable-next-line import/extensions
const { compilerOptions } = require('./tsconfig.json');

// module.exports = { ...
moduleNameMapper: pathsToModuleNameMapper(compilerOptions.paths),
// ...

但是，我仍然有相同的行为: intellisense甚至没有像上面列出的那样加载可能的自定义路径，在下面的图像中可以看到：

这种情况发生在此文件夹结构中：

Answer 1

您可以为构建创建一个新的tsconfig文件。示例:将当前的tsconfig.json复制到tsconfig.build.json

记住在serverless.ts中更新esbuild选项

...
custom: {
    esbuild: {
        tsconfig: 'tsconfig.build.ts'
    }
}
...

然后为IDE(vscode)创建一个新的tsconfig.json并进行测试：

{
  "extends": "./tsconfig.paths.json", // extend setting from build config
 
  "include": [
    "src/**/*.ts",
    "tests/**/*.ts" // include tests directory
  ],
  "exclude": [
    "node_modules/**/*",
    ".serverless/**/*",
    ".webpack/**/*",
    "_warmup/**/*",
    ".vscode/**/*"
  ]
}
