# Firefly-iii Service {#services-firefly-iii}
Defined in [`/modules/services/firefly-iii.nix`](@REPO@/modules/services/firefly-iii.nix).
This NixOS module is a service that sets up a [Firefly-iii](https://www.firefly-iii.org/) instance.
Compared to the stock module from nixpkgs,
this one sets up, in a fully declarative manner,
LDAP and SSO integration
and has a nicer option for secrets.
It also sets up the Firefly-iii data importer service
and nearly automatically links it to the Firefly-iii instance using a Personal Account Token.
Instructions on how to do so is given in the next section.
## Features {#services-firefly-iii-features}
- Integration with the [dashboard contract](contracts-dashboard.html) for displaying user facing application in a dashboard. [Manual](#services-firefly-iii-usage-applicationdashboard)
## Usage {#services-firefly-iii-usage}
### Initial Configuration {#services-firefly-iii-usage-configuration}
The following snippet assumes a few blocks have been setup already:
- the [secrets block](usage.html#usage-secrets) with SOPS,
- the [`shb.ssl` block](blocks-ssl.html#usage),
- the [`shb.lldap` block](blocks-lldap.html#blocks-lldap-global-setup).
- the [`shb.authelia` block](blocks-authelia.html#blocks-sso-global-setup).
```nix
shb.firefly-iii = {
enable = true;
debug = false;
appKey.result = config.shb.sops.secret."firefly-iii/appKey".result;
dbPassword.result = config.shb.sops.secret."firefly-iii/dbPassword".result;
domain = "example.com";
subdomain = "firefly-iii";
siteOwnerEmail = "mail@example.com";
ssl = config.shb.certs.certs.letsencrypt.${domain};
smtp = {
host = "smtp.eu.mailgun.org";
port = 587;
username = "postmaster@mg.example.com";
from_address = "firefly-iii@example.com";
password.result = config.shb.sops.secret."firefly-iii/smtpPassword".result;
};
sso = {
enable = true;
authEndpoint = "https://${config.shb.authelia.subdomain}.${config.shb.authelia.domain}";
};
importer = {
# See note hereunder.
# firefly-iii-accessToken.result = config.shb.sops.secret."firefly-iii/importerAccessToken".result;
};
};
shb.sops.secret."firefly-iii/appKey".request = config.shb.firefly-iii.appKey.request;
shb.sops.secret."firefly-iii/dbPassword".request = config.shb.firefly-iii.dbPassword.request;
shb.sops.secret."firefly-iii/smtpPassword".request = config.shb.firefly-iii.smtp.password.request;
# See not hereunder.
# shb.sops.secret."firefly-iii/importerAccessToken".request = config.shb.firefly-iii.importer.firefly-iii-accessToken.request;
```
Secrets can be randomly generated with `nix run nixpkgs#openssl -- rand -hex 64`.
Note that for `appKey`, the secret length must be exactly 32 characters.
The [user](#services-firefly-iii-options-shb.firefly-iii.ldap.userGroup)
and [admin](#services-firefly-iii-options-shb.firefly-iii.ldap.adminGroup)
LDAP groups are created automatically.
Only admin users have access to the Firefly-iii data importer.
On the Firefly-iii web UI, the first user to login will be the admin.
We cannot yet create multiple admins in the Firefly-iii web UI.
On first start, leave the `shb.firefly-iii.importer.firefly-iii-accessToken` option empty.
To fill it out and connect the data importer to the Firefly-iii instance,
you must first create a personal access token then fill that option and redeploy.
### Backup {#services-firefly-iii-usage-backup}
Backing up Firefly-iii using the [Restic block](blocks-restic.html) is done like so:
```nix
shb.restic.instances."firefly-iii" = {
request = config.shb.firefly-iii.backup;
settings = {
enable = true;
};
};
```
The name `"firefly-iii"` in the `instances` can be anything.
The `config.shb.firefly-iii.backup` option provides what directories to backup.
You can define any number of Restic instances to backup Firefly-iii multiple times.
You will then need to configure more options like the `repository`,
as explained in the [restic](blocks-restic.html) documentation.
### Certificates {#services-firefly-iii-certs}
For Let's Encrypt certificates, add:
```nix
{
shb.certs.certs.letsencrypt.${domain}.extraDomains = [
"${config.shb.firefly-iii.subdomain}.${config.shb.firefly-iii.domain}"
"${config.shb.firefly-iii.importer.subdomain}.${config.shb.firefly-iii.domain}"
];
}
```
### Impermanence {#services-firefly-iii-impermanence}
To save the data folder in an impermanence setup, add:
```nix
{
shb.zfs.datasets."safe/firefly-iii".path = config.shb.firefly-iii.impermanence;
}
```
### Declarative LDAP {#services-firefly-iii-declarative-ldap}
To add a user `USERNAME` to the user and admin groups for Firefly-iii, add:
```nix
shb.lldap.ensureUsers.USERNAME.groups = [
config.shb.firefly-iii.ldap.userGroup
config.shb.firefly-iii.ldap.adminGroup
];
```
### Application Dashboard {#services-firefly-iii-usage-applicationdashboard}
Integration with the [dashboard contract](contracts-dashboard.html) is provided
by the [dashboard option](#services-firefly-iii-options-shb.firefly-iii.dashboard).
For example using the [Homepage](services-homepage.html) service:
```nix
{
shb.homepage.servicesGroups.Finance.services.Firefly-iii = {
sortOrder = 1;
dashboard.request = config.shb.firefly-iii.dashboard.request;
settings.widget.type = "firefly";
};
}
```
The widget type needs to be set manually otherwise it is not displayed correctly.
An API key can be set to show extra info:
```nix
{
shb.homepage.servicesGroups.Finance.services.Firefly-iii = {
apiKey.result = config.shb.sops.secret."firefly-iii/homepageApiKey".result;
};
shb.sops.secret."firefly-iii/homepageApiKey".request =
config.shb.homepage.servicesGroups.Finance.services.Firefly-iii.apiKey.request;
}
```
## Database Inspection {#services-firefly-iii-database-inspection}
Access the database with:
```nix
sudo -u firefly-iii psql
```
Dump the database with:
```nix
sudo -u firefly-iii pg_dump --data-only --inserts firefly-iii > dump
```
## Mobile Apps {#services-firefly-iii-mobile}
This module was tested with the [Abacus iOS](https://github.com/victorbalssa/abacus) mobile app
using a Personal Account Token.
