65 | 66 | ## Features 67 | 68 | - Includes 5 different log levels (`trace`, `debug`, `info`, `warn` & `error`) 69 | - Colorized output 70 | - No external dependencies 71 | - Returns the value provided for cleaner logging 72 | - Only logs during development 73 | 74 | ## Install 75 | 76 | ```sh 77 | $ npm install react-native-log-level 78 | # OR 79 | $ yarn add react-native-log-level 80 | ``` 81 | 82 | ## Usage 83 | 84 | ```js 85 | import createLogger from 'react-native-log-level' 86 | 87 | // Create a instance 88 | const log = createLogger({ 89 | level: 'info' // Optionally set the log level. Defaults to 'info' 90 | }) 91 | 92 | const obj = { 93 | foo: 1, 94 | bar: 2 95 | } 96 | 97 | log.trace('hi') 98 | log.debug('hi') 99 | log.info('hi', obj) 100 | log.warn('hi', obj) 101 | log.error('hi') 102 | ``` 103 | 104 | Since the value logged is returned, cleaner logging is possible 105 | 106 | ```js 107 | 108 | if (log.info(it === anotherThing)) { 109 | // Do Stuff 110 | } 111 | 112 | ``` 113 | 114 | ## Contributing 115 | 116 | Contributions are welcome! 117 | 118 | 1.
