如何使用 Node 和 TypeScript 获取异步堆栈跟踪？

Question

我希望我可以在 TypeScript 中获得堆栈跟踪。我似乎只看到最底层的函数名称。我在 Windows 10 (1803) 上使用 Node.js v12.4.0。

这是代码：

async function thrower() {
  throw new Error("test");
}

async function level1() {
  return await thrower();
}

async function level2() {
  return await level1();
}

async function level3() {
  return await level2();
}

async function main() {
  try {
    await level3();
  } catch(err) {
    console.warn("main error", err);
  }
}

console.log("node version", process.version);

main().then(() => {
  console.log("all done " + __filename);
}).catch((err) => {
  console.error("Something went wrong in here :(", __filename, err);
})

得到的堆栈跟踪没有提及level1或level2或level3：

async function thrower() {
  throw new Error("test");
}

async function level1() {
  return await thrower();
}

async function level2() {
  return await level1();
}

async function level3() {
  return await level2();
}

async function main() {
  try {
    await level3();
  } catch(err) {
    console.warn("main error", err);
  }
}

console.log("node version", process.version);

main().then(() => {
  console.log("all done " + __filename);
}).catch((err) => {
  console.error("Something went wrong in here :(", __filename, err);
})

Answer 1

经过一些研究并注意到__awaiter，我决定检查什么是 TypeScript 目标。那是我的问题。

这是我的坏处tsconfig.json：

{
    "compilerOptions": {
      "experimentalDecorators": true,
      "emitDecoratorMetadata": true,
      "downlevelIteration": true,
    },
    "include": [
        "server/**/*", "tests"
    ],
    "exclude": [
        "node_modules",
        "**/*.spec.ts"
    ]
}

这"target": "es2018"修复了它：

{
    "compilerOptions": {
      "experimentalDecorators": true,
      "emitDecoratorMetadata": true,
      "downlevelIteration": true,
      "target": "es2018"
    },
    "include": [
        "server/**/*", "tests"
    ],
    "exclude": [
        "node_modules",
        "**/*.spec.ts"
    ]
}

导致此堆栈跟踪：

{
    "compilerOptions": {
      "experimentalDecorators": true,
      "emitDecoratorMetadata": true,
      "downlevelIteration": true,
    },
    "include": [
        "server/**/*", "tests"
    ],
    "exclude": [
        "node_modules",
        "**/*.spec.ts"
    ]
}
