# FireQL
`FireQL` is the Golang library and interactive CLI tool to query the Google Firestore database using SQL syntax.
It is built on top of the official [Google Firestore Client SDK](https://pkg.go.dev/cloud.google.com/go/firestore) that will allow running queries Cloud Firestore database using SQL syntax. Inspired by [Firebase FireSQL](https://firebaseopensource.com/projects/jsayol/firesql/).

## Usage
`FireQL` can be used as Go library or interactive command-line tool.
### Go Library
An example of querying collections using SQL syntax:
```go
import (
"github.com/pgollangi/fireql"
)
func main() {
fql, err := fireql.New("")
//OR
fql, err = fireql.New("", fireql.OptionServiceAccount(""))
if err != nil {
panic(err)
}
// Now, execute SELECT query
result, err := fql.Execute("SELECT * `users` order by id desc limit 10")
if err != nil {
panic(err)
}
_ = result
}
```
### Command-Line
```bash
fireql [flags]
```
#### Example
```bash
$ fireql --project $PROJECT_ID
Welcome! Use SQL to query Firestore.
Use Ctrl+D, type "exit" to exit.
Visit github.com/pgollangi/FireQL for more details.
fireql>select id, name from users limit 2
+------+------------+
| ID | NAME |
+------+------------+
| 1046 | bob |
| 1047 | smith |
+------+------------+
(2 rows)
fireql>
```
Read the [documentation](https://pgollangi.github.io/FireQL/) for more information on CLI usage.
## Examples
Some cool `SELECT` queries that are possible with `FireQL`:
```sql
select * from users
select * from `[contacts]` // To query collection group. enclose subcollect name in square brackets.
select *, id as user_id from users
select id, email as email_address, `address.city` AS city from `users`
select * from users order by 'address.city' desc limit 10
select * from `users` where id > 50
select id, LENGTH(contacts) as total_contacts from `users`
select id, (age > 100) as centenarian as total_contacts from `users`
select __name__ from users // to select document id
```
`FireQL` depend on [govaluate](https://github.com/Knetic/govaluate) to evaluate expressions in `SELECT`. See list of possible expressions and operators [here](https://github.com/Knetic/govaluate/blob/master/MANUAL.md#operators).
See [Wiki](https://github.com/pgollangi/FireQL/wiki) for more examples.
### Authentication
`fireql.New` assume Google [Application Default Credentials](https://cloud.google.com/docs/authentication/application-default-credentials) to authenticate to Firestore database if `serverAccount` not passed. Otherwise use service account for authentication.
## Installation
### Homebrew
```bash
brew install pgollangi/tap/fireql
```
Updating:
```bash
brew upgrade fireql
```
### Scoop (for windows)
```sql
scoop bucket add pgollangi-bucket https://github.com/pgollangi/scoop-bucket.git
scoop install fireql
```
### Docker
```bash
docker run pgollangi/fireql
```
### Go
```bash
go install github.com/pgollangi/fireql@latest
```
### Manual
You can alternately download a suitable binary for your OS at the [releases page](https://github.com/pgollangi/fireql/releases).
## Limitations
All of [firestore query limitations](https://firebase.google.com/docs/firestore/query-data/queries#query_limitations) are applicable when running queries using `FireQL`.
In addition to that:
- Only `SELECT` queries for now. Support for `INSERT`, `UPDATE`, and `DELETE` might come in the future.
- Only `AND` conditions supported in `WHERE` clause.
- No support for `JOIN`s.
- `LIMIT` doesn't accept an `OFFSET`, only a single number.
- No support of `GROUP BY` and aggregate function `COUNT`.
## Future scope
- [x] Create an interactive command-line shell to run queries
- [ ] Expand support for all logical conditions in `WHERE` clause by internally issuing multiple query requests to Firestore and merging results locally before returning.
- [ ] `GROUP BY` support
- [ ] Support other DML queries: `INSERT`, `UPDATE`, and `DELETE`
## Run
### Tests
```shell
$ go test ./...
```
