go-gallery

Pre

  1. Install Go
  2. Install Docker
  3. Install Docker-Compose

Clone and install deps

$ git clone [email protected]:gallery-so/go-gallery.git
$ cd go-gallery
$ go get -u=patch -d ./...

Setup (Mac)

$ go build -o ./bin/main ./cmd/server/main.go

This will generate a binary within ./bin/main. To run the binary, simply run:

$ ./bin/main

Redis and Postgres

The app will connect to a local redis and local postgres instance by default. To spin it up, you can use the docker commands below.

[Optional] Shell script to seed NFT data

If you want to seed your local database with real, indexed data from our dev or production clusters, you can "prep" your environment using the following bash script. Running this won't execute the import itself, but rather trigger the import when you run the later docker commands. As a pre-requisite, you must have access to _encrypted_deploy in order to access the dev / prod clusters.

Note that if you run the following command, don't run make g-docker and upload the image to Dockerhub. This will expose the locally migrated data to the public. You can avoid this by opening a new shell. More on make g-docker further below.

Finally: if you are using bash/sh instead of zsh, change the first line of the _import_env.sh file to match your shell.

$ source ./_import_env.sh <path to dev/prod backend app.yaml> <address of dev/prod wallet to import data>

Docker commands

Build the docker containers. If you ran the above shell script, the seed script will be executed. You can re-run this script in the future if you want the latest data:

$ make docker-build

Run the docker containers:

$ make docker-start

To remove running redis and postgres instance:

$ make docker-stop

Working with migrations

The migrate cli can be installed via brew (assuming MacOS):

brew install golang-migrate

Create a new migration:

# New migration for the backend db
migrate create -ext sql -dir db/migrations/core -seq <name of migration>

Run a migration locally:

# Run all migrations for the local backend db
make migrate-coredb

Run a migration on dev backend db:

# Apply an up migration to the backend db
migrate -path db/migrations/core -database "postgresql://postgres:<dev db password here>@34.102.59.201:5432/postgres" up

# Undo the last migration to the backend db
migrate -path db/migrations/core -database "postgresql://postgres:<dev db password here>@34.102.59.201:5432/postgres" down 1

Healthcheck

Verify that the server is running:

$ curl localhost:4000/alive

This is available for live environments:

$ curl api.gallery.so/alive

## Testing

Run all tests in current directory and all of its subdirectories:

```bash
$ go test ./...

Run all tests in subdirectory (e.g. /server):

$ go test ./server/...

Run a specific test by passing including the -run flag. The example will run GraphQL tests under the TestMain suite that start with "should get trending".

go test -run=TestMain/"test GraphQL"/"should get trending" ./graphql

Add -v for detailed logs.

Skip longer running tests with the -short flag:

go test -short

Running locally with live data

If you have access to the _encrypted_local file, you can run the server locally with live data. This is useful for testing the server locally with real data.

For example, to run the server locally with live data from the dev environment, run the following command:

go run cmd/server/main.go dev
# Do not switch the order of the buckets! Doing so may overwrite prod data.
gsutil -m rsync -r gs://prod-eth-token-logs gs://dev-eth-token-logs

Root CAs for RPC

These are the added certificates that are included in the _deploy folder. They are used to verify the SSL certificates of various HTTPS endpoints.
