Mirror a hyperdrive or localdrive into another one
npm install mirror-driveMirror a Hyperdrive or Localdrive into another one
``
npm i mirror-drive
`js
import MirrorDrive from 'mirror-drive'
const src = new Localdrive('./src')
const dst = new Hyperdrive(store)
const mirror = new MirrorDrive(src, dst)
console.log(mirror.count) // => { files: 0, add: 0, remove: 0, change: 0 }
for await (const diff of mirror) {
console.log(diff) /* {
op: 'add',
key: '/new-file.txt',
bytesRemoved: 0,
bytesAdded: 4
}*/
}
console.log(mirror.count) // => { files: 1, add: 1, remove: 0, change: 0 }
`
Another example:
`js
const mirror = new MirrorDrive(src, dst)
console.log(mirror.count) // => { files: 0, add: 0, remove: 0, change: 0 }
await mirror.done()
console.log(mirror.count) // => { files: 1, add: 1, remove: 0, change: 0 }

#### const mirror = new MirrorDrive(src, dst, [options])
Creates a mirror instance to efficiently move src drive into dst drive.
Available options:
`js`
{
prefix: '/',
dryRun: false,
prune: true,
includeEquals: false,
filter: (key) => true,
metadataEquals: (srcMetadata, dstMetadata) => { ... }
batch: false,
entries: null // Array of key entries (if you use this then prefix is ignored)
ignore: String || Array // Ignore source files and folders by name.
transformers: [] // Array of factory functions (key) => stream
}
#### mirror.count
It counts the total files proccessed, added, removed, and changed.
Default value: { files: 0, add: 0, remove: 0, change: 0 }
#### await mirror.done()
It starts processing all the diffing until is done.
Apply content transformers during mirroring. Each item in transformers is a factory function (key) => stream | null that returns a new stream (or null) for that file. MirrorDrive always pipes through all provided transformers. If a transformer returns null` it is safely skipped.
