简单的同步或异步错误处理包装器，让 try catch 见鬼去吧。

English · 简体中文

安装

pnpm add @cceevv/tryit
# or
yarn add @cceevv/tryit
# or
npm i @cceevv/tryit

开发

pnpm install
pnpm build
pnpm test

使用

import tryit from "@cceevv/tryit";

function syncDemo() {
  const DefaultValue = { a: 0, b: "" };
  const [data = DefaultValue, err] = tryit(() => {
    return JSON.parse('--------{"a":1234, "b":"bbb"}');
  });
  if (err) {
    console.log("xxxxxxxxxx", err);
    return;
  }
  console.log("handle data...", data);
}

async function asyncDemo() {
  const promise = new Promise((resolve, reject) => {
    resolve("resolve data");
    // reject('reject error');
  });

  const [data, err] = await tryit(() => promise);
  if (err) {
    console.log("xxxxxxxxxx", err);
    return;
  }
  console.log("handle data...", data);
}

async function followedReturnedPromise() {
  const [data, err] = await tryit(async () => {
    return Promise.resolve(666);
  });
  if (err) {
    console.log("xxxxxxxxxx", err);
    return;
  }
  console.log("handle data...", data);
}

接口

export type TryitResult<T, U = Error> = [T, null] | [undefined, U];

export declare function tryit<T, U = Error>(func: () => T): TryitResult<T, U>;
export declare function tryit<T, U = Error>(
  func: () => PromiseLike<T>,
): Promise<TryitResult<T, U>>;

tryit 只接受函数。异步值也需要包装成 () => promise。传入无效参数时会抛出 TypeError。
