loggych

Logger abstraction and console realization

ILoggych

//Universal logger abstraction

export interface LoggychConf {
    debug: boolean;
    info: boolean;
    warn: boolean;
    err: boolean;
}

export interface ILoggych
{
    log(vals: Partial<Record<keyof LoggychConf, any>>): Promise<void>;
    logCustom(vals: Record<string, any>): Promise<void>;
    addContext(...any: any[]): ILoggych;
    switchConf(keys: LoggychConf): ILoggych;
}

export const logErrConf = {err: true, debug: false, info: false, warn: false};
export const logWarnConf = {err: true, debug: false, info: false, warn: true};
export const logInfoConf = {err: true, debug: false, info: true, warn: true};
export const logDebugConf = {err: true, debug: true, info: true, warn: true};

expo

ConsoleLoggych

//Console logger realization

export class ConsoleLoggych implements ILoggych
{
    public constructor(conf: LoggychConf, context: any[] = []);

    private consoleLog(v: any): void;

    log(vals: Partial<LoggychConf>): Promise<void>;

    logCustom(vals: Record<string, any>): Promise<void>;

    public switchConf(keys: LoggychConf): ILoggych;

    public addContext(...any: any[]): ILoggych;
}

Test:

//This script:
const log = (new ConsoleLoggych(logDebugConf)).addContext("test run")
const val: any = {a: 12, b: 'asdasd"', c: [{a: 123}, BigInt(123124), false, null, undefined]}
val.d = val
await log.log({debug: ["Logging info", val]})
await log.addContext("Another context", 12).log({err: new Error("test error")})

//Will print his debug line:

//test run
//debug:
//Logging info {"a":12,"b":"asdasd\"","c":[{"a":123},"123124",false,null,null],"d":"[Circular]"}
//
//test run
//Another context 12
//err:
//{
//  message: 'test error',
//  name: 'Error',
//  stack: 'Error: test error\n' +
//    '    at D:\\js-projects\\loggych\\js\\scripts\\test-loggych.js:53:91\n' +
//    '    at step (D:\\js-projects\\loggych\\js\\scripts\\test-loggych.js:33:23)\n' +
//    '    at Object.next (D:\\js-projects\\loggych\\js\\scripts\\test-loggych.js:14:53)\n' +
//    '    at fulfilled (D:\\js-projects\\loggych\\js\\scripts\\test-loggych.js:5:58)\n' +
//    '    at processTicksAndRejections (internal/process/task_queues.js:97:5)'
//}

HtmlElemLoggych

//Logger, logging into innerHtml of html elem

export declare class HtmlElemLoggych implements ILoggych

    log(vals: Partial<Record<keyof LoggychConf, any>>): Promise<void>;

    logCustom(vals: Record<string, any>): Promise<void>;

    addContext(...any: any[]): ILoggych;

    static createDefault(elem: HTMLElement, debug?: boolean, context?: any[]): HtmlElemLoggych;
}

ComposeLoggych

Loggych, that logs message into mutiple other loggyches

export type ComposeLoggychConf = {
    info: ILoggych[];
    debig: ILoggych[];
    err: Iloggych[];
    warn: ILoggych[];
    custom: Iloggych[];
}

 */

{
    constructor(conf: ComposeLoggychConf, context?: any[]);

    addContext(...any: any[]): ILoggych;

    switchConf(keys: LoggychConf): ILoggych;

    log(vals: Partial<Record<keyof LoggychConf, any>>): Promise<void>;

    logCustom(vals: Record<string, any>): Promise<void>;

    static makeAllLogsForAllMsgs(logs: ILoggych[], context?: any[]): ILoggych;
}
