@ -18,6 +18,38 @@ Do not modify `config/default.js`, but instead create a copy at `config/local.js
You can also use `npm run flush` to run both steps at once, and wipe the database completely later.
#### Networks and channels
To scrape the networks and channels available in the database, you can configure `include` and `exclude` lists. To include all available channels and only use the `exclude` list, leave the `include` parameter unconfigured. The `exclude` lists will exclude channels and child networks from networks on the `include` lists, but not vice versa. That is, if the `include` list includes a network and the `exclude` list excludes one of that network's channels, the channel will not be scraped. However, if the `include` list includes a channel, and the `exclude` list includes its parent network, the channel will be scraped.
This configuration will scrape Evil Angel and all XEmpire channels, except for LesbianX.
```
include: {
networks: [
'xempire',
],
channels: [
'evilangel',
],
},
exclude: {
channels: [
'lesbianx',
],
}
```
This configuration will scrape all channels, except for BAM Visions, and except all channels part of the Vixen network.
```
exclude: {
channels: [
'bamvisions',
],
networks: [
'vixen'
],
},
```
