Nidus Sync

This is the software that powers Nidus Cloud Sync.

Building from source

First, you'll need Nix.

Then:

nix develop
go build .

Running

You'll need a number of environment variables for configuring things;

• ARCGIS_CLIENT_ID - The client ID for ArcGIS oauth, configured with esri.
• ARCGIS_CLIENT_SECRET - The client secret for ArcGIS oauth, configured with esri.
• BASE_URL - The URL the site is hosted at, used for forming callback URLs. Should be complete like 'https://foo.bar'
• BIND - The address and port to bind to. Use ':9001' for 'any address, port 9001'
• ENVIRONMENT - either 'PRODUCTION' or 'DEVELOPMENT'. It's used to set things like oauth token length.
• MAPBOX_TOKEN - The token to use with mapbox which is important for rendering maps.
• POSTGRES_DSN - The DSN for connecting to the postgres database.
• FIELDSEEKER_SCHEMA_DIRECTORY - The directory to write fieldseeker schema files for debugging.
• USER_FILES_DIRECTORY - The directory for writing uploaded user data files (audio, images).

> BASE_URL=https://sync.nidus.cloud ARCGIS_CLIENT_ID=foo ARCGIS_CLIENT_SECRET=bar POSTGRES_DSN='postgresql://?host=/var/run/postgresql&dbname=nidus-sync' ./nidus-sync

Districts

There's a table containing district information in the database, import.district. It was created with:

psql
CREATE SCHEMA import;
shp2pgsql -s 3857 -c -D -I CA_districts.shp import.district | psql -d nidus-sync
psql
ALTER TABLE import.district ADD COLUMN geom_4326 geometry(MultiPolygon,4326) GENERATED ALWAYS AS (ST_Transform(geom, 4326)) STORED;

Hacking

air

This project uses air for fast compile-and-test loops. You can run it with:

> BASE_URL=https://sync.nidus.cloud ARCGIS_CLIENT_ID=foo ARCGIS_CLIENT_SECRET=bar POSTGRES_DSN='postgresql://?host=/var/run/postgresql&dbname=nidus-sync' air

bob

This uses the bob query framework. You can regenerate the models for bob with:

PSQL_DSN="postgresql://dbname?host=/var/run/postgresql&sslmode=disable" go run github.com/stephenafamo/bob/gen/bobgen-psql@latest"
PSQL_DSN="postgresql://?host=/var/run/postgresql&sslmode=disable&dbname=nidus-sync" go run github.com/stephenafamo/bob/gen/bobgen-psql@latest

This will generate a bunch of files. They're already committed, you only need this if you change the database schema in some way.

goose

This uses goose. You can use the goose command line to check status and make changes

> cd migrations
> GOOSE_DRIVER=postgres GOOSE_DBSTRING="dbname=nidus-sync sslmode=disable" goose status
> GOOSE_DRIVER=postgres GOOSE_DBSTRING="dbname=nidus-sync sslmode=disable" goose down
> GOOSE_DRIVER=postgres GOOSE_DBSTRING="dbname=nidus-sync sslmode=disable" goose up
