// This is hacky webpack loader that does string replacements to
// allow lmdb@2 to be bundled by webpack for engines.
// Currently `@vercel/webpack-asset-relocator-loader doesn't handle
// the way lmdb is loading binaries and dictionary file
// (can't statically analyze it). So we perform few localized changes
// and we replace dynamic values with hardcoded ones to allow
// asset-relocator to pick those assets up and handle them.
//
// Because lmdb code can diverge, we also pin version in gatsby
// dependencies and will have manually bump it (with renovate most likely).
//
// To solve this upstream few things would need to change:
//  - https://github.com/DoctorEvidence/lmdb-js/blob/544b3fda402f24a70a0e946921e4c9134c5adf85/node-index.js#L14-L16
//  - https://github.com/DoctorEvidence/lmdb-js/blob/544b3fda402f24a70a0e946921e4c9134c5adf85/open.js#L77
// Reliance on `import.meta.url` + usage of `.replace` is what seems to cause problems currently.
