gobin is a simple lightweight haste-server alternative written in Go, HTML, JS and CSS. It is aimed to be easy to use and deploy. You can find an instance running at xgob.in.

• Easy to deploy and use
• Built-in rate-limiting
• Create, update and delete documents
• Syntax highlighting
• Document expiration
• Supports PostgreSQL or SQLite
• One binary and config file
• Docker image available
• Metrics (to be implemented)

The easiest way to deploy gobin is using docker with Docker Compose. You can find the docker image on Packages.

Create a new docker-compose.yml file with the following content:

Note You should change the password in the docker-compose.yml and gobin.json file.

version: "3.8"

services:
  gobin:
    image: ghcr.io/topisenpai/gobin:latest
    container_name: gobin
    restart: unless-stopped
    volumes:
      - ./gobin.json:/var/lib/gobin/gobin.json
      # use this for sqlite
      - ./gobin.db:/var/lib/gobin/gobin.db
    ports:
      - 80:80

  # or use this for postgres
  postgres:
    image: postgres:latest
    container_name: postgres
    restart: unless-stopped
    volumes:
      - ./data:/var/lib/postgresql/data
    environment:
      POSTGRES_DB: gobin
      POSTGRES_USER: gobin
      POSTGRES_PASSWORD: password

For gobin.json/environment variables and database schema see Configuration.

docker-compose up -d

• Go 1.18 or higher
• PostgreSQL 13 or higher

git clone https://github.com/TopiSenpai/gobin.git
cd gobin
go build -o gobin

or

go install github.com/TopiSenpai/gobin@latest

gobin --config=config.json

The database schema is automatically created when you start gobin and there is no documents table in the database.

Create a new gobin.json file with the following content:

Note Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".

{
  "dev_mode": false,
  "debug": false,
  "listen_addr": "0.0.0.0:80",
  # secret for jwt tokens, replace with a long random string
  "jwt_secret": "...",
  "database": {
    # either "postgres" or "sqlite"
    "type": "postgres",
    "debug": false,
    "expire_after": "168h",
    "cleanup_interval": "10m",

    # path to sqlite database
    # if you run gobin with docker make sure to set it to "/var/lib/gobin/gobin.db"
    "path": "gobin.db",

    # postgres connection settings
    "host": "localhost",
    "port": 5432,
    "username": "gobin",
    "password": "password",
    "database": "gobin",
    "ssl_mode": "disable"
  },
  # max document size in characters
  "max_document_size": 0,
  # omit or set values to 0 or "0" to disable rate limit
  "rate_limit": {
    # number of requests which can be done in the duration
    "requests": 10,
    # the duration of the requests
    "duration": "1m"
  }
}

Alternatively you can use environment variables to configure gobin. The environment variables are prefixed with GOBIN_ and are in uppercase. For example GOBIN_DATABASE_TYPE or GOBIN_RATE_LIMIT_REQUESTS.

GOBIN_DEV_MODE=false
GOBIN_DEBUG=false
GOBIN_LISTEN_ADDR=0.0.0.0:80
GOBIN_JWT_SECRET=...

GOBIN_DATABASE_TYPE=postgres
GOBIN_DATABASE_DEBUG=false
GOBIN_DATABASE_EXPIRE_AFTER=168h
GOBIN_DATABASE_CLEANUP_INTERVAL=10m

GOBIN_DATABASE_PATH=gobin.db

GOBIN_DATABASE_HOST=localhost
GOBIN_DATABASE_PORT=5432
GOBIN_DATABASE_USERNAME=gobin
GOBIN_DATABASE_PASSWORD=password
GOBIN_DATABASE_DATABASE=gobin
GOBIN_DATABASE_SSL_MODE=disable

GOBIN_MAX_DOCUMENT_SIZE=0

GOBIN_RATE_LIMIT_REQUESTS=10
GOBIN_RATE_LIMIT_DURATION=1m

Following endpoints are rate-limited:

• POST /documents
• PATCH /documents/{key}
• DELETE /documents/{key}

PATCH and DELETE share the same bucket while POST has it's own bucket

To create a paste you have to send a POST request to /documents with the content as plain/text body.

Note You can also specify the code language with the Language header.

Language: go

package main

func main() {
    println("Hello World!")
}

A successful request will return a 200 OK response with a JSON body containing the document key and token to update the document.

{
  "key": "hocwr6i6",
  "version": 1,
  "token": "kiczgez33j7qkvqdg9f7ksrd8jk88wba"
}

To get a document you have to send a GET request to /documents/{key}.

The response will be a 200 OK with the document content as application/json body.

{
  "key": "hocwr6i6",
  "version": "1",
  "data": "package main\n\nfunc main() {\n    println(\"Hello World!\")\n}",
  "language": "go"
}

To get a documents versions you have to send a GET request to /documents/{key}/versions?withData={bool}.

The response will be a 200 OK with the document content as application/json body.

[
  {
    "version": 1,
    "data": "package main\n\nfunc main() {\n    println(\"Hello World!\")\n}",
    "language": "go"
  },
  {
    "version": 2,
    "data": "package main\n\nfunc main() {\n    println(\"Hello World2!\")\n}",
    "language": "go"
  }
]

To get a document version you have to send a GET request to /documents/{key}/versions/{version}.

The response will be a 200 OK with the document content as application/json body.

{
  "key": "hocwr6i6",
  "version": 1,
  "data": "package main\n\nfunc main() {\n    println(\"Hello World!\")\n}",
  "language": "go"
}

To update a paste you have to send a PATCH request to /documents/{key} with the content as plain/text body and the token as Authorization header.

Note You can also specify the code language with the Language header.

Authorization: kiczgez33j7qkvqdg9f7ksrd8jk88wba
Language: go

package main

func main() {
    println("Hello World Updated!")
}

A successful request will return a 200 OK response with a JSON body containing the document key and token to update the document.

Note The update token will not change after updating the document. You can use the same token to update the document again.

{
  "key": "hocwr6i6",
  "version": 2
}

To delete a document you have to send a DELETE request to /documents/{key} with the token as Authorization header.

A successful request will return a 204 No Content response with an empty body.

To delete a document version you have to send a DELETE request to /documents/{key}/versions/{version} with the token as Authorization header.

A successful request will return a 204 No Content response with an empty body.

• GET /raw/{key} - Get the raw content of a document
• GET /raw/{key}/{version} - Get the raw content of a document version
• HEAD /raw/{key} - Get the raw content of a document without the body
• HEAD /raw/{key}/{version} - Get the raw content of a document version without the body
• GET /ping - Get the status of the server
• GET /debug - Proof debug endpoint (only available in debug mode)
• GET /version - Get the version of the server

In case of an error gobin will return the following JSON body with the corresponding HTTP status code:

{
  "message": "document not found", # error message
  "status": 404, # HTTP status code
  "path": "/documents/7df3vw", # request path
  "request_id": "fbe0a365387f/gVAMGuraLW-003490" # request id
}
