pino-ui

This library is an improvement of pino-pretty. Sometimes it's too complicated to browse through console logs and understand all logs on a specific request.

This library adds a web view for the pino logs.

Installation

npm install pino-ui --save-dev

Usage

The usage is similar to pino-pretty which is quite simple, all you need to do is pipe to pino-ui.

node server.js | pino-ui

Configuration

You can configure:

• The columns you want to display on the table
• The columns you want to display on the details and how to display them
• Which column has a request identifier or trace id
• The port it's going to use to serve the UI

We're using JSON to read the configuration.

Important: You need to add the json file with the following name (.pino-ui.json) on the cwd of your application

| Field | Type | Description | | ------------------- | ------- | ------------------------------------------------------------ | | gridColumns | Column | How to display the grid columns | | detailColumns | Column | How to display the log data on the details | | traceColumn | String | The column used for trace so we can easily separate all logs in a single trace | | port | Number | The port to serve the UI (Default 8080) | | autoReset | Boolean | If auto reset when process is restarted, default to false | | ascending | Boolean | Wether sorting will be ascending or not, default to false (descending) | | chartWindowMinute | Number | Window to capture number of logs in the log chart. Default to 1 (minute) |

Column Type

| Field | Type | Description | | ----------- | ------ | ------------------------------------------------------------------------------------------- | | name | String | Label of the column | | key | String | The key we're going to use to render the column | | formatter | String | text, multiline_text, numeric, code, sql, json, uuid, duration, timestamp |
