Haste

Haste is an open-source pastebin software written in node.js, which is easily installable in any network. It can be backed by either redis or filesystem, and has a very easy adapter interface for other stores. A publicly available version can be found at hastebin.com

Major design objectives:

  • Be really pretty
  • Be really simple
  • Be easy to set up and use

Haste works really well with a little utility called haste-client, allowing you to do things like:

cat something | haste

which will output a URL to share containing the contents of cat something's STDOUT. Check the README there for more details and usages.

Tested Browsers

  • Firefox 8
  • Chrome 17
  • Safari 5.3

Installation

  1. Download the package, and expand it
  2. Explore the settings inside of config.js, but the defaults should be good
  3. npm install
  4. npm start (you may specify an optional <config-path> as well)

Settings

  • host - the host the server runs on (default localhost)
  • port - the port the server runs on (default 7777)
  • keyLength - the length of the keys to user (default 10)
  • maxLength - maximum length of a paste (default 400000)
  • staticMaxAge - max age for static assets (86400)
  • recompressStaticAssets - whether or not to compile static js assets (true)
  • documents - static documents to serve (ex: http://hastebin.com/about.com) in addition to static assets. These will never expire.
  • storage - storage options (see below)
  • logging - logging preferences
  • keyGenerator - key generator options (see below)
  • rateLimits - settings for rate limiting (see below)

Rate Limiting

When present, the rateLimits option enables built-in rate limiting courtesy of connect-ratelimit. Any of the options supported by that library can be used and set in config.js.

See the README for connect-ratelimit for more information!

Key Generation

Phonetic

Attempts to generate phonetic keys, similar to pwgen

{
  "type": "phonetic"
}

Random

Generates a random key

{
  "type": "random",
  "keyspace": "abcdef"
}

The optional keySpace argument is a string of acceptable characters for the key.

Storage

File

To use file storage (the default) change the storage section in config.js to something like:

{
  "path": "./data",
  "type": "file"
}

where path represents where you want the files stored.

File storage currently does not support paste expiration, you can follow #191 for status updates.

Redis

To use redis storage you must install the redis package in npm, and have redis-server running on the machine.

npm install redis

Once you've done that, your config section should look like:

{
  "type": "redis",
  "host": "localhost",
  "port": 6379,
  "db": 2
}

You can also set an expire option to the number of seconds to expire keys in. This is off by default, but will constantly kick back expirations on each view or post.

All of which are optional except type with very logical default values.

If your Redis server is configured for password authentification, use the password field.

Postgres

To use postgres storage you must install the pg package in npm

npm install pg

Once you've done that, your config section should look like:

{
  "type": "postgres",
  "connectionUrl": "postgres://user:password@host:5432/database"
}

You can also just set the environment variable for DATABASE_URL to your database connection url.

You will have to manually add a table to your postgres database:

create table entries (id serial primary key, key varchar(255) not null, value text not null, expiration int, unique(key));

You can also set an expire option to the number of seconds to expire keys in. This is off by default, but will constantly kick back expirations on each view or post.

All of which are optional except type with very logical default values.

MongoDB

To use mongodb storage you must install the 'mongodb' pachage in npm

npm install mongodb

Once you've done that, your config section should look like:

{
  "type": "mongodb",
  "connectionUrl": "mongodb://localhost:27017/database"
}

You can also just set the environment variable for DATABASE_URL to your database connection url.

Unlike with postgres you do NOT have to create the table in your mongo database prior to running.

You can also set an expire option to the number of seconds to expire keys in. This is off by default, but will constantly kick back expirations on each view or post.

Memcached

To use memcache storage you must install the memcached package via npm

npm install memcached

Once you've done that, your config section should look like:

{
  "type": "memcached",
  "host": "127.0.0.1",
  "port": 11211
}

You can also set an expire option to the number of seconds to expire keys in. This behaves just like the redis expirations, but does not push expirations forward on GETs.

All of which are optional except type with very logical default values.

RethinkDB

To use the RethinkDB storage system, you must install the rethinkdbdash package via npm

npm install rethinkdbdash

Once you've done that, your config section should look like this:

{
  "type": "rethinkdb",
  "host": "127.0.0.1",
  "port": 28015,
  "db": "haste"
}

In order for this to work, the database must be pre-created before the script is ran. Also, you must create an uploads table, which will store all the data for uploads.

You can optionally add the user and password properties to use a user system.

Google Datastore

To use the Google Datastore storage system, you must install the @google-cloud/datastore package via npm

npm install @google-cloud/datastore

Once you've done that, your config section should look like this:

{
  "type": "google-datastore"
}

Authentication is handled automatically by Google Cloud service account credentials, by providing authentication details to the GOOGLE_APPLICATION_CREDENTIALS environmental variable.

Amazon S3

To use Amazon S3 as a storage system, you must install the aws-sdk package via npm:

npm install aws-sdk

Once you've done that, your config section should look like this:

{
  "type": "amazon-s3",
  "bucket": "your-bucket-name",
  "region": "us-east-1"
}

Authentication is handled automatically by the client. Check Amazon's documentation for more information. You will need to grant your role these permissions to your bucket:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "s3:GetObject",
                "s3:PutObject"
            ],
            "Effect": "Allow",
            "Resource": "arn:aws:s3:::your-bucket-name-goes-here/*"
        }
    ]
}

Docker

Build image

docker build --tag haste-server .

Run container

For this example we will run haste-server, and connect it to a redis server

docker run --name haste-server-container --env STORAGE_TYPE=redis --env STORAGE_HOST=redis-server --env STORAGE_PORT=6379 haste-server

Use docker-compose example

There is an example docker-compose.yml which runs haste-server together with memcached

docker-compose up

The docker image is configured using environmental variables as you can see in the example above.
