# go-coinbase-fetcher
#### A simple go library delegated to store the history from coinbase.com for any given currency
## Functionalities:
- The `Downloader` have the following parameter: `Granularity`, `Pair`, `LimitDate`:
- Granularity: 60, 300, 900, 3600, 21600, 86400;
- Pair: coinbase pair;
- Limit date: stop date (download all from now since `limit date`);
- The `Downloader` create a `csv` file using the input parameter, an
example: `BTC-USD-86400-2015-01-01T00:00:00Z-2022-02-28T00:39:03Z.csv`;
- The `csv` file created is processed in streaming. Once that a `batch` of 300 rows have been downloaded, the result is
store into the file; serialized as `csv`;
Example:
```go
// ...
var opts = datastructure.DownloadOpts{
Granularity: datastructure.GRANULARITY_DAY,
Pair: "BTC-USD",
LimitDate: time.Date(2015, 01, 01, 0, 0, 0, 0, time.UTC),
}
// ...
```
#### Once initialized, the downloader is delegated to download the data for the given pair in the given period
```go
download := opts.New()
filename := download.Download(nil)
```
#### A progressbar will show the number estimated finish time and other information:
```text
2021-08-09T00:30:00Z 7% |█████████████████ | (65/836, 5 it/s) [15s:2m34s]
```
