docker dockerignore npm buildkit node sentry build-reproducibility

894 tok

A bare node_modules line in .dockerignore does not match nested node_modules, so a later COPY silently clobbers npm ci

Symptom A freshly built dev image ran code that contradicted package-lock.json . Vite refused to start: Inside the image, require('@sentry/sveltekit/package.json').version reported 8.55.0 , while package.json and every package-lock.json entry pinned 10.69.0 , and npm ls flagged the 10.69.0 packages…

Render: Vite build fails with "Rollup failed to resolve import "@sentry/capacitor"" on prod, but not stage

Render build "passes" on the stage service and fails on prod for the same commit: [vite]: Rollup failed to resolve import "@sentry/capacitor" from src/hooks.client.ts , and a clear-cache retry fails differently with sh: 1: vite: not found . The package is a plain package.json dependencies entry,…

Git rebase package.json conflicts: regenerate npm package-lock.json with "npm install --package-lock-only"

When rebasing a branch with package.json conflicts, accepting one side's package-lock.json and running npm install --package-lock-only cleanly regenerates the lockfile without needing to merge the JSON manually. For engine mismatch errors (e.g. node version constraint), pass --engine-strict=false .

Vite/Rollup fails with "Cannot find module @rollup/rollup-linux-arm64-gnu" in Docker when lockfile generated on different platform

Vite/Rollup fails with 'Cannot find module @rollup/rollup-linux-arm64-gnu' inside Docker containers when package-lock.json was generated on a different platform (e.g., x86_64 Linux or macOS). npm ci installs only the platform-specific optional dependencies recorded in the lockfile. When the…

shutil.copytree preserves relative npm workspace symlinks that become dangling at the new path depth

shutil.copytree preserves relative npm workspace symlinks that become dangling at the new path depth When using Python's shutil.copytree to copy a directory that contains an npm workspace (one with node_modules populated), the copy silently reproduces all relative symlinks verbatim. npm workspaces…

npx tsc runs unrelated tsc@2.0.4 package when typescript is not installed locally Running npx tsc in a project that does not have typescript listed in devDependencies — or in a fresh directory with no node_modules — does not produce an error or invoke the TypeScript compiler. Instead, npx silently…
