评估 JavaScript

Deno Sandbox provides a sandboxed Linux microVM. This is useful for evaluating code that is not trusted or for testing code that is not safe to run in your main runtime.

你可以使用 eval 函数在沙箱中评估 JavaScript 代码。

import { Sandbox } from "@deno/sandbox";

await using sandbox = await Sandbox.create();

const result = await sandbox.deno.eval(`
  const a = 1;
  const b = 2;
  a + b;
`);
console.log("result:", result);

调用 sandbox.deno.eval() 允许你直接在沙箱的 Deno 运行时中运行任意 JavaScript 代码片段，而无需编写文件或调用外部命令。这在你想快速原型化逻辑、运行小型计算或检查沙箱环境时非常有用。适用于动态脚本或探索性调试，当创建完整模块显得过于繁琐时。
