We fight for democratic values, freedom, for our future! Once again Ukrainians have to stand against evil, terror, against genocide. The outcome of this war will determine what path human history is taking from now on.
💛💙 Help Ukraine! We need your support! There are [dozen ways][ukr-link] to help us, just do it!
There are a lot of cases where you need to parse and analyze your logs. For example, to access them during tests. This package provides transport that allows simply push logs to js array, so you don't need any runtime parsers anymore.
To use library you need to have node and npm installed in your machine:
* node >=10
* npm >=6
Package is [continuously tested][node-ver-test-url] on darwin, linux and win32 platforms. All active and maintenance LTS node releases are supported.
To install the library run the following command
``bash`
npm i --save winston-array-transport
The package can be used alongside any other [winston transport][w-transports].
`javascript
import ArrayTransport from 'winston-array-transport';
import { createLogger } from 'winston';
const logs = [];
const transport = new ArrayTransport({ array: logs, json: true, level: 'info' });
export const logger = createLogger({
transports : [ transport ]
});
`Configuration
Next options can be configured while transport creation:
* name - name of a transport, `ArrayTransport` by default;`
* eol - end of line , os.EOL` by default;`
* array - array, where all logs will be stored;
parser - function*, that will be applied to log messages;
* json - if set to true`, `JSON.parse` parser will be used;`
* limit - allows to limit amount of logs to n`` last items;
