Or in an app: `import { VERSION } from '@angular/fire'; console.log(VERSION.full);`\n\n### Expected behavior\n\n`VERSION.full` (and the underlying `Version` object in `src/core.ts`) should report the real installed version, e.g. `21.0.0-rc.0`.\n\n### Actual behavior\n\n`VERSION` is constructed as `new Version('ANGULARFIRE2_VERSION')` - the build-time placeholder that's supposed to be replaced with the real version before publishing, but isn't for this occurrence. The published package ships the literal string.\n\nA related mechanism is also broken: `src/schematics/versions.json`'s `peerDependencies`/`firebaseFunctionsDependencies` data is filled in by `tools/build.ts` *after* the schematics are bundled with esbuild, which has already inlined the JSON import from the unfilled source file at compile time.\n- The post-build edit to `versions.json` on disk is never read by the shipped schematic code.\n- One concrete effect: `addDependencies()` in `src/schematics/common.ts` never has real version data to check against, so it can't detect or warn about conflicting dependency versions the way it appears designed to.\n\nWill need a decision on one of these approaches:\n- string-replace with a build-time guard, matching what PR #3709/#3711 just did for the schematics' own version placeholder, or\n- reworking the `versions.json` inlining - the fix touches `tools/build.ts` and possibly `src/core.ts`, so I wanted to flag it and get a read before picking a direction.\n","author":{"url":"https://github.com/armando-navarro","@type":"Person","name":"armando-navarro"},"datePublished":"2026-07-15T19:42:20.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/3715/angularfire/issues/3715"}
