# bot-api
## Introduction
The function of the API is basically to access the images' metadata stored in the database.
## Usage
The API exposes some endpoints to interact with the database.
### GET `/images`
Allows to get a list of image documents.
#### Query params
- `limit`: an optional parameter, which accepts a non-negative integer that dictates the number of documents that the list will have. If its value is equal to `0`, or if this parameter is missing, the endpoint will return all the image documents in the database.
- `status`: an optional parameter, which accepts the values `consumed`, `available` and `unavailable`. It filters the documents that have only the `status` attribute equal to that indicated in the parameter's value. If the parameter is missing, no filter will be applied to the document.
#### Example
- `GET /images?limit=5&status=available` will return 5 documents that have the `available` value in their `status` attribute.
### GET `/images/<id>`
Allows to get an image document.
#### Params
- `id`: the id of the document to be modified.
#### Example
`GET /images/61f7e48f0c651345677b7775` will get the document referenced by the `id` param.
### PUT `/images/<id>`
Modifies an existing image document. The request must provide a JSON-formatted body, with one or more valid document attributes. The existing document attributes will be replaced with the provided new ones.
#### Params
- `id`: the id of the document to be modified.
#### Example
- `PUT /images/61f7e48f0c651345677b7775` with body `{ "status": "consumed" }` will modify the document referenced by the `id` param, changing their `status` value to `consumed`.
### POST `/images`
Allows to insert a new image document.
#### Example
`POST /images` with body `{ "url": "https://my-images.com/foo.jpg", "status": "available", "tags": ["foo", "bar"] }` will insert the image passed on the request body into the database.
### POST `/login`
Generates an access token to use in future requests to authenticated endpoints if a valid App and Secret are provided.
#### Example
`POST /login` with body `{ "app": "example", "secret": "badsecret" }` will return `{ "token": "x.y.z" }` "x.y.z" being a JWT token to use on further requests if the App and Secret are valid.
## Installation
To install dependencies:
```bash
@ -9,13 +56,13 @@ bun install
To run:
```bash
docker compose up
bun run dev
```
For testing, remember:
```bash
docker compose down -v
docker compose run bot-api bun run test
bun run test
```
This project was created using `bun init` in bun v1.0.13. [Bun](https://bun.sh) is a fast all-in-one JavaScript runtime.
