Axios Logger Interceptor
Log request and response, redact all possible PII sources by default, but allow to add custom redact paths so more info can be logged.
Using
yarn add @ovotech/axios-logger
import { axiosLogger, redactHeader } from '@ovotech/axios-logger';
import axios from 'axios';
const logger = axiosLogger((level, meta, config) => console.log(level, meta, config.url));
const api = axios.create();
api.interceptors.request.use(logger.request.onFullfilled);
api.interceptors.response.use(logger.response.onFullfilled, logger.response.onRejected);
// ...
api.get('/my/path');
const body = { user: { cards: [{ id: '111' }, { id: '222' }] } };
api.post('/update/path', body, { headers: { [redactHeader]: 'requestBody.user.cards.*.id' } });
You have 3 interceptors. logger.request.onFullfilled
, logger.response.onFullfilled
and logger.response.onRejected
.
logger.request.onFullfilled
used to setup the initial execution time. If omitted request time would not be logged.logger.response.onFullfilled
logs a successful responselogger.response.onRejected
logs an error
Each one can be omitted if you don't want or need that feature.
The log function will receive 3 arguments - level, meta and axios request config. The first one indicates what type of log level to use - "info" for success and "error" for error. The second contains an object of data to log.
{
uri: '/my/path',
method: 'get',
params: { id: '10' }
requestBody: { id: '10' },
responseBody: { user: 'Name' },
status: 200,
responseTime: 21,
}
By default uri
, params
, requestBody
and responseBody
will be "redacted", since they can contain personally identifiable information. You can control that with the redactHeader
. Its a comma separated list of dot delimited field paths to be redacted. Can contain wildcard *
path to target all array items.
For example to redact some fields.
api.post('/update/path', body, { headers: { [redactHeader]: 'requestBody.id, responseBody.user' });
You can also set redact at the axios instance level for global redaction rules:
const api = axios.create({ redact: ['requestBody'] });
Granular logging
You can perform different things on error / success by inspecting the "level" argument, passed to the log function.
import { axiosLogger } from '@ovotech/axios-logger';
import axios from 'axios';
const logger = axiosLogger((level, meta) => {
if (level === 'info') {
myOwnLogger.info('Successful request', meta);
graphResponseTimes(meta.responseTime);
}
if (level === 'error') {
myOwnLogger.error('Error request', meta);
}
});
Running the tests
You can run the tests with:
yarn test
Coding style (linting, etc) tests
Style is maintained with prettier and tslint
yarn lint
Deployment
Deployment is preferment by lerna automatically on merge / push to master, but you'll need to bump the package version numbers yourself. Only updated packages with newer versions will be pushed to the npm registry.
