All error classes used in node_redis from v.3.0.0 are in here. They can be required as needed.
Install with NPM:
npm install redis-errors
t { ReplyError, InterruptError } = require('redis-errors');
sing async await
{
ait client.set('foo') // Missing value
tch (err) {
(err instanceof InterruptError) {
console.error('Command might have been processed')
(err instanceof ReplyError) {
// ...
row err
sing callbacks
nt.set('foo', (err, res) => {
(err) {
if (err instanceof InterruptError) {
// ...
}
All errors returned by NodeRedis use own Error classes. You can distinguish different errors easily by checking for these classes.
To know what caused the error they might contain properties to know in more detail what happened.
Each error contains a message
, a name
and a stack
property. Please be aware
that the stack might not be useful due to the async nature and is in those cases
therefore limited to two frames.
There might be more not yet documented properties as well. Please feel free to open a pull request to document those as well.
Properties
:
Properties depend on the individual error.
All errors returned by NodeRedis (client) are RedisError
s.
Subclass of Error
Properties
:
args
: The arguments passed to the command.command
: The command name.code
: The Redis
error code. Redis itself uses some internal error codes.All errors returned by Redis itself (server) will be a ReplyError
.
Subclass of RedisError
Properties
:
buffer
: The raw buffer input stringified.offset
: The character count where the parsing error occurred.Parsing errors are returned as ParserError
.
Subclass of RedisError
Note: If you encounter one of these please report that error including the
attached offset
and buffer
properties!
Properties
:
args
: The arguments passed to the command.command
: The command name.If a command was not yet executed but rejected, it'll return a AbortError
.
Subclass of RedisError
Properties
:
args
: The arguments passed to the command.command
: The command name.origin
: The original error that caused the interruptAll executed commands that could not fulfill (e.g. network drop while
executing) return a InterruptError
.
Subclass of AbortError
Note: Interrupt errors can happen for multiple reasons that are out of the
scope of NodeRedis itself. There is nothing that can be done on library side
to prevent those.
