…235) Closes #220. What does this PR do / solve? ----------------------------- When developing and/or testing features (e.g. the "load more" button, see #221) in a local environment, it can be handy to have some posts in the local database. Overview of changes ------------------- Introduce `./scripts/import-from-prod.js` which loads [adrien's profile and posts](https://openwhyd.org/adrien) to the local/testing database. How to test this PR? -------------------- Run this after starting a local database server (e.g. with `$ docker-compose up`): ```sh $ node scripts/import-from-prod.js ``` => http://localhost:8080/all should display several pages of tracks imported from https://openwhyd.org/adrien.
