Firebase Functions Lister

Staticly lists the Firebase Functions you have in your local Firebase Project

Pre-requisites:

• Node modules for the function must be installed
• If you're using TypeScript, it must be complied to JavaScript

How to use

Getting Firebase Functions config

const { loadFunctionsConfig } = require("./lib");

async function main() {
  // Change "__tests__/firebase-proj" to relative path to your Firebase Project folder
  const functionCodebaseConfig = await loadFunctionsConfig(
    "__tests__/firebase-proj"
  );
  console.log(JSON.stringify(functionCodebaseConfig, null, 2));
}

main();

Outputs:

    "source": "functions",
    "codebase": "default",
    "main": "index.js",
    "functions": {
      "groups.groupedFunctionJs01": {

    ]
  },
  ...

Getting list of deploy commands

async function main() {
  const functionCodebaseConfig = await loadFunctionsConfig(
    "./__tests__/firebase-proj"
  );

  const deployCommands = getFunctionsDeployCommands(functionCodebaseConfig);
  console.log(deployCommands);
}

main();

Outputs:

[
  "functions:default:groups.groupedFunctionJs01",
  "functions:default:groups.groupedFunctionJs02",
  "functions:default:helloWorldJs01",
  "functions:default:onDocWrittenJs01",
  "functions:second-codebase:grouped.helloWorldTsGrouped01",
  "functions:second-codebase:helloWorldTs01",
  "functions:second-codebase:helloWorldTs02",
  "functions:third-codebase:groups.groupedHelloWorldJsEs01",
  "functions:third-codebase:groups.groupedHelloWorldJsEs02",
  "functions:third-codebase:helloWorldJsEs01"
