ckochandClaude Opus 5 b69a5c9d14 Add library export and import
The only backup was the Docker volume. Export writes the caller's whole
library as JSON or CSV; import reads either back, into the same account or
a different one.

Rows are matched on title + system rather than id, so a file is portable
between accounts and instances, and the same game on three consoles stays
three entries. Merge adds and updates but deletes nothing. Replace wipes
first, and is gated behind an explicit confirm dialog in the UI. dryRun
reports what would happen and writes nothing.

CSV is hand-rolled rather than pulling a dependency, but handles the parts
that actually bite: quoted fields containing commas, escaped quotes,
embedded newlines and CRLF endings. That is not hypothetical here — 101 of
the 105 descriptions contain newlines, and two titles contain accents, so a
naive split-on-comma would corrupt most of the library. Exports carry a BOM
so Excel reads them as UTF-8.

Verified against the real library, not just fixtures: 105 games exported to
CSV, imported into a scratch account and re-exported compare identical
field for field.

15 new tests cover round-trip fidelity, merge vs replace, dry run,
per-user isolation on the destructive path, malformed input, and the
awkward-quoting case. 51 backend tests total.

LudosWeb

This project was generated using Angular CLI version 22.1.2.

Development server

To start a local development server, run:

ng serve

Once the server is running, open your browser and navigate to http://localhost:4200/. The application will automatically reload whenever you modify any of the source files.

Code scaffolding

Angular CLI includes powerful code scaffolding tools. To generate a new component, run:

ng generate component component-name

For a complete list of available schematics (such as components, directives, or pipes), run:

ng generate --help

Building

To build the project run:

ng build

This will compile your project and store the build artifacts in the dist/ directory. By default, the production build optimizes your application for performance and speed.

Running unit tests

To execute unit tests with the Vitest test runner, use the following command:

ng test

Running end-to-end tests

For end-to-end (e2e) testing, run:

ng e2e

Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.
