replace-stack-traces

A JavaScript function to replace error stack traces and following Node.js versions at any indent in a multiline string.

Useful for snapshot testing CLI stderr output containing error stack traces, because:

• Different Node.js versions generate different error stack traces, and v17.0.0+ appends the Node.js version if the error caused the process to exit.
• Editing modules that affect the line and column numbers, etc. in the error stack traces requires the snapshots to be updated annoyingly often.

Installation

For Node.js, to install replace-stack-traces with npm, run:

npm install replace-stack-traces

For Deno, an example import map:

{
  "imports": {
    "replace-stack-traces": "https://unpkg.com/[email protected]/replaceStackTraces.mjs"
  }
}

Requirements

Supported runtime environments:

• Node.js versions ^14.17.0 || ^16.0.0 || >= 18.0.0.
• Deno

Non Deno projects must configure TypeScript to use types from the ECMAScript modules that have a // @ts-check comment:

• compilerOptions.allowJs should be true.
• compilerOptions.maxNodeModuleJsDepth should be reasonably large, e.g. 10.
• compilerOptions.module should be "node16" or "nodenext".

Exports

The npm package replace-stack-traces features optimal JavaScript module design. These ECMAScript modules are exported via the package.json field exports:

• replaceStackTraces.mjs
