#### 🚀 **FastGCP** is the faster, more intuitive way of working with Google Cloud Platform services and frameworks.

#### The `fastgcp` package is built on top of canonical Google Python packages(s) without any alteration to Google's base code.

#### ~**Full documentation can be found** [here](https://tomathon.dev/articles/fastgcp)~ (WIP)


-----

## **Installation**

**fastgcp** is installed using pip with the command:

`$ pip install fastgcp`


-----

## **The `BigQuery` class**

#### One of the main **FastGCP** classes is `BigQuery`. It allows users to work with BQ database tables and objects in a more ***Pythonic*** way.

## **Quickstart**

#### Import `BigQuery`:

```python
from fastgcp import BigQuery
```

#### Initialize `BigQuery` using your GCP Project name:

```python
bq = BigQuery(project_id = "gcp-project-name")
```

#### Alternatively, to initialize using a specific service account key, pass the full key path to your `key.json`:

```python
bq = BigQuery(
    project_id = "gcp-project-name",
    service_acct_key_path = "/full/path/to/your/service/account/key.json"
)
```


## **Common `BigQuery` Methods:**

## `bq.read_bigquery`

### _Read an existing BigQuery table into a DataFrame_

#### `read_bigquery(bq_dataset_dot_table = None, date_cols = [], preview_top = None, to_verbose = True)`

- **bq_dataset_dot_table** : the "dataset-name.table-name" path of the existing BigQuery table
- **date_cols** : [optional] column(s) passed inside a list that should be parsed as dates
- **preview_top** : [optional] only read in the top ***N*** rows
- **to_verbose** : should info be printed? defaults to **True**
- **use_polars** : should a `polars` DataFrame be returned instead of a `pandas` DataFrame? Defaults to **True**

### EX:

```python
my_table = bq.read_bigquery("my_bq_dataset.my_bq_table")

my_table = bq.read_bigquery("my_bq_dataset.my_bq_table", date_cols = ['date'])
```


### -----------


## `bq.read_custom_query`
### _Read an existing BigQuery table into a DataFrame, using a custom SQL expression_

#### `read_custom_query(custom_query, to_verbose = True)`

- **custom_query** : the custom BigQuery SQL query that will produce a table to be read into a DataFrame
- **to_verbose** : should info be printed? defaults to **True**
- **use_polars** : should a `polars` DataFrame be returned instead of a `pandas` DataFrame? Defaults to **True**

### EX:

```python
my_custom_table = bq.read_custom_query("""
    SELECT
        date,
        sales,
        products
    FROM
        my_bq_project_id.my_bq_dataset.my_bq_table
    WHERE
        sales_month = 'June'
""")
```


### -----------


## `bq.write_bigquery`
### _Write a DataFrame to BigQuery_

#### `write_bigquery(df, bq_dataset_dot_table = None, use_schema = None, append_to_existing = False, to_verbose = True)`

- **df** : the DataFrame to be written to a BigQuery table
- **bq_dataset_dot_table** : the "dataset-name.table-name" path of the existing BigQuery table
- **use_schema** : [optional] a custom schema for the BigQuery table. **NOTE**: see **bq.guess_schema** below
- **append_to_existing** : should the DataFrame be appended to an existing BigQuery table? defaults to **False** (create new / overwrite)
- **to_verbose** : should info be printed? defaults to **True**

### EX:

```python
bq.write_bigquery(my_df, "my_bq_dataset.my_data")

bq.write_bigquery(my_df, "my_bq_dataset.my_data", append_to_existing = True)
```


### -----------


## `bq.send_query`
### _Send a custom SQL query to BigQuery. Process is carried out within BigQuery. Nothing is returned_

#### _send_query(que, to_verbose = True)_

- **que** : the custom SQL query to be sent and carried out within BigQuery
- **to_verbose** : should info be printed? defaults to **True**

### EX:

```python
bq.send_query("""
    CREATE TABLE my_bq_project_id.my_bq_dataset.my_new_bq_table AS 
    (
        SELECT
            date,
            sales,
            products
        FROM
            my_bq_project_id.my_bq_dataset.my_bq_table
        WHERE
            sales_month = 'June'
    )
""")
```
