### Data Directories and Paths

By default, `orbit-db` creates a data directory `./orbitdb` under which metadata of databases is stored along with the actual data blocks saved in IPFS. The metadata can be found under `./orbitdb/QmFoo/database.orbitdb` for each database. The data blocks saved in IPFS are in `./orbitdb/ipfs`.

To use another `orbit-db` data directory (as opposed to the default `./orbitdb`), set `ORBITDB_PATH` environment variable to point to the desired data directory. Eg. run the CLI with `ORBITDB_PATH=/path/orbitdb orbitdb ...`

To use `orbit-db` with an existing IPFS data repository, set the `IPFS_PATH` environment variable to the desired IPFS repository path. Eg. run the CLI with `IPFS_PATH=/path/to/ipfs orbitdb ...`

## Demo

```
node ./src/cli/bin demo FRANK!
```

Output:

## Replicate

### For `eventlog` or `feed` type databases

Demo:

Run in the terminal:

```
orbitdb create a eventlog
```

Copy the address the above command output. Eg. `/orbitdb/QmQxfgdjo3EQZiqBgt4uDiJNoLNedRNCZTHCquohxScsXc/a`.

In a second terminal, run:

```
mkdir tmp/ && cd tmp/
orbitdb replicate <address> --progress
```

*Eg. `orbitdb replicate /orbitdb/QmQxfgdjo3EQZiqBgt4uDiJNoLNedRNCZTHCquohxScsXc/a --progress --dashboard`*

Output:
```
Replicating '/orbitdb/QmQxfgdjo3EQZiqBgt4uDiJNoLNedRNCZTHCquohxScsXc/a'
░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ 0/0 |   0.0% | 00:00:00
```

In the first terminal, run:
```
orbitdb add <address> hi! -r --sync --interval 1000
```

Observe the database replicating to the second instance.

Output:
```
Replicating ██████████████████████████░░░░░░░░░░░░░░ 2/3 |  66.7% | 00:00:21
```

```
Replicating ████████████████████████████████████████ 77/77 |  100.0% | 00:02:31
```
### For `docstore` type databases

First, create a database and add an item to it:

```
$ node src/bin.js create /orbitdb/mydocstore docstore                         ~
/orbitdb/QmapaF6FmS3JgTQBKSpSZUdqgf2t8VUUvXcUCdPd5MaeQB/orbitdb/mydocstore
$ node src/bin.js put /orbitdb/QmapaF6FmS3JgTQBKSpSZUdqgf2t8VUUvXcUCdPd5MaeQB/orbitdb/mydocstore '{"name": "foo", "_id": 1}' --indexBy name
Added document 'foo'
```

You may now syncrhonise it with another. To do that, run `replicate` on the current directory as well as in the directory you want to synchronise with. Both should result in the same output:

```
$ node src/bin.js replicate /orbitdb/QmapaF6FmS3JgTQBKSpSZUdqgf2t8VUUvXcUCdPd5MaeQB/orbitdb/mydocstore --progress
Swarm listening on /ip4/127.0.0.1/tcp/38795/ipfs/QmRvDCjRzBB9PjkcCRJQFBDS8V8hsfivpQGFUh85ERxQeM

```

## Dev

*Random notes*

```
node src/bin.js import 2017.csv /t9 src/schemas/csv-schema1.js --progress --limit 5000 --indexBy name
```
