Once fetched, dependencies can be installed via `go get` or (the preferred method) at specific versions via `golang/dep`, the prototype golang pakcage manager. Installation instructions are [here](https://golang.github.io/dep/docs/installation.html).
In order to install packages with `dep`, ensure you are in the project directory now within your `GOPATH` (default location is `~/go/src/github.com/vulcanize/vulcanizedb/`) and run:
`dep ensure`
After `dep` finishes, dependencies should be installed within your `GOPATH` at the versions specified in `Gopkg.toml`.
Lastly, ensure that `GOPATH` is defined in your shell. If necessary, `GOPATH` can be set in `~/.bashrc` or `~/.bash_profile`, depending upon your system. It can be additionally helpful to add `$GOPATH/bin` to your shell's `$PATH`.
In some cases (such as recent Ubuntu systems), it may be necessary to overcome failures of password authentication from localhost. To allow access on Ubuntu, set localhost connections via hostname, ipv4, and ipv6 from peer/md5 to trust in: /etc/postgresql/<version>/pg_hba.conf
- Copy `environments/local.toml.example` to `environments/local.toml` to configure commands to run against a local node such as [Ganache](https://truffleframework.com/ganache) or [ganache-cli](https://github.com/trufflesuite/ganache-clihttps://github.com/trufflesuite/ganache-cli).
To provide data for transformations, raw Ethereum data must first be synced into vDB.
This is accomplished through the use of the `lightSync`, `sync`, or `coldImport` commands.
These commands are described in detail [here](https://github.com/vulcanize/maker-vulcanizedb/blob/readme/documentation/sync.md).
### Data transformation
Contract watchers use the raw data that has been synced into Postgres to filter out and apply transformations to specific data of interest.
There is a built-in `contractWatcher` command which provides generic transformation of most contract data. This command is described in detail [here](https://github.com/vulcanize/maker-vulcanizedb/blob/readme/documentation/contractWatcher.md).
In many cases a custom transformer or set of transformers will need to be written to provide complete or more comprehensive coverage or to optimize other aspects of the output for a specific end-use.
In this case we have provided the `compose`, `execute`, and `composeAndExecute` commands for running custom transformers from external repositories. This is described in detail [here](https://github.com/vulcanize/maker-vulcanizedb/blob/readme/documentation/composeAndExecute.md).
- Replace the empty `ipcPath` in the `environments/infura.toml` with a path to a full archival node's eth_jsonrpc endpoint (e.g. local geth node ipc path or infura url)
1. you will need to make sure you have ssh agent running and your ssh key added to it. instructions [here](https://developer.github.com/v3/guides/using-ssh-agent-forwarding/#your-key-must-be-available-to-ssh-agent)
[Postgraphile](https://www.graphile.org/postgraphile/) is used to expose GraphQL endpoints for our database schemas, this is described in detail [here](../staging/postgraphile/README.md).
