tea.xyz Spam Plagues npm and RubyGems Package Registries
Tea.xyz, a crypto project aimed at rewarding open source contributions, is once again facing backlash due to an influx of spam packages flooding public package registries.
sails-redis-lite
Advanced tools
Readme
A light Sails/Waterline adapter for Redis. May be used in a Sails app or anything using Waterline for the ORM.
Base on the sails-redis, remove the indexes and unique constraints, add expire time support.
I develop it for caching complicated models datas which has a lot of associations.
Install is through NPM.
$ npm install sails-redis-lite
The following connection configuration is available:
// default values inline
config: {
port: 6379,
host: 'localhost',
password: null,
database: null
};
Alternatively the URL notation for configuration can be used for configuration:
config {
url: 'redis://h:abc123@host.com:6379'
}
// Equivalent to:
// config: {
// port: 6379,
// host: 'host.com'
// password: 'abc123'
// }
// Other portions of the URL, including the 'username' 'h' are ignored
Note that if both the 'url' notation and the 'host', 'port' and / or 'password' notations are used, the non-url configuration options will take precedence.
When using this library with sails add the config below to your config/connections.js
file:
redis: {
adapter: "sails-redis-lite",
port: 6379,
host: 'localhost'
}
And then you can make it the default by changing config/models.js
to show:
connection: 'redis',
Configuration for the underlying Redis driver itself is located as an object under the options
. The following options are available:
parser
: which Redis protocol reply parser to use. Defaults to hiredis
if that module is installed.
This may also be set to javascript
.return_buffers
: defaults to false
. If set to true
, then all replies will be sent to callbacks as node Buffer
objects instead of JavaScript Strings.detect_buffers
: default to false
. If set to true
, then replies will be sent to callbacks as node Buffer objects
if any of the input arguments to the original command were Buffer objects.
This option lets you switch between Buffers and Strings on a per-command basis, whereas return_buffers
applies to
every command on a client.socket_nodelay
: defaults to true
. Whether to call setNoDelay() on the TCP stream, which disables the
Nagle algorithm on the underlying socket. Setting this option to false
can result in additional throughput at the
cost of more latency. Most applications will want this set to true
.no_ready_check
: defaults to false
. When a connection is established to the Redis server, the server might still
be loading the database from disk. While loading, the server not respond to any commands. To work around this,
node_redis
has a "ready check" which sends the INFO
command to the server. The response from the INFO
command
indicates whether the server is ready for more commands. When ready, node_redis
emits a ready
event.
Setting no_ready_check
to true
will inhibit this check.enable_offline_queue
: defaults to true
. By default, if there is no active
connection to the redis server, commands are added to a queue and are executed
once the connection has been established. Setting enable_offline_queue
to
false
will disable this feature and the callback will be execute immediately
with an error, or an error will be thrown if no callback is specified.retry_max_delay
: defaults to null
. By default every time the client tries to connect and fails time before
reconnection (delay) almost doubles. This delay normally grows infinitely, but setting retry_max_delay
limits delay
to maximum value, provided in milliseconds.connect_timeout
defaults to false
. By default client will try reconnecting until connected. Setting connect_timeout
limits total time for client to reconnect. Value is provided in milliseconds and is counted once the disconnect occured.max_attempts
defaults to null
. By default client will try reconnecting until connected. Setting max_attempts
limits total amount of reconnects.auth_pass
defaults to null
. By default client will try connecting without auth. If set, client will run redis auth command on connect.See FAQ.md
