device-definitions-api

device-definitions-api

Api for managing device definitions on the DIMO platform.

For an overview of the project, see the DIMO technical documentation site.

Developing locally

TL;DR

cp settings.sample.yaml settings.yaml
docker compose up -d
go run ./cmd/device-definitions-api migrate
go run ./cmd/device-definitions-api

Generating client and server code

1. Install the protocol compiler plugins for Go using the following commands

brew install protobuf
go install google.golang.org/protobuf/cmd/protoc-gen-go
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest

1. Run protoc in the root directory

protoc --go_out=. --go_opt=paths=source_relative \
    --go-grpc_out=. --go-grpc_opt=paths=source_relative \
    pkg/grpc/*.proto

Linting

brew install golangci-lint

golangci-lint run

This should use the settings from .golangci.yml, which you can override.

If brew version does not work, download from https://github.com/golangci/golangci-lint/releases (darwin arm64 if M1), then copy to /usr/local/bin and sudo xattr -c golangci-lint

Database ORM

This is using sqlboiler. The ORM models are code generated. If the db changes, you must update the models.

Make sure you have sqlboiler installed:

go install github.com/volatiletech/sqlboiler/v4@latest
go install github.com/volatiletech/sqlboiler/v4/drivers/sqlboiler-psql@latest

To generate the models:

sqlboiler psql --no-tests --wipe

Make sure you're running the docker image (ie. docker compose up)

If you get a command not found error with sqlboiler, make sure your go install is correct. Instructions here

Adding migrations

To install goose in GO:

$ go get github.com/pressly/goose/v3/cmd/goose@v3.5.3
export GOOSE_DRIVER=postgres

To install goose CLI:

$ go install github.com/pressly/goose/v3/cmd/goose
export GOOSE_DRIVER=postgres

Have goose installed, then:

goose -dir internal/infrastructure/db/migrations create slugs-not-null sql

Loading Data

Importing data: Device definition exports are here You can use sqlboiler to import or this command:

psql "host=localhost port=5432 dbname=device_definitions_api user=dimo password=dimo" -c "\COPY device_definitions_api.integrations (id, type, style, vendor, created_at, updated_at, refresh_limit_secs, metadata) FROM '/Users/aenglish/Downloads/drive-download-20221020T172636Z-001/integrations.csv' DELIMITER ',' CSV HEADER"
