static-console

Keep structure of the messages and log them to any output, using specific plugins.

Install

$ npm install static-console --save --only=production

Recommended option --only=production to skip installation of testing environment. If you want to test it, don't put this option.

API

StaticConsole

const c = require('static-console');

logt(type, ...obj)

Log message with data ...obj under specified type.

type - message type name. null value means that message has regular type.

...obj - parameters that represent the whole message separated by commas

c.logt('special-message-type', `This message is printed under specific type`);
c.logt('multiple-objects', `PI value:`, Math.PI);

It will output:

This message is printed under specific type
PI value: 3.141592653589793

log(...obj)

Same as c.logt(null, ...obj).

error(...obj)

Same as c.logt('error', ...obj).

warn(...obj)

Same as c.logt('warn', ...obj).

info(...obj)

Same as c.logt('info', ...obj).

silly(...obj)

Same as c.logt('silly', ...obj).

trace(title)

Same as c.logt('trace', c.traceStr(title)).

traceStr(title)

Returns stack trace for your debug needs. title replaces caption on first line, by default it will be Trace.

reset(namespace, displayTitle, params)

Set namespace for all next messages.

namespace - string or undefined. When defined string, represents namespace. When undefined, messages gonna be printed in global namespace.

displayTitle - string with display title for last name.

params - object with other options for last name. Very optional.

Namespace is splitted by c.namespaceNestingSymbol ('-' by default) to inherited names, so you can return to parent name without specifying displayTitle and params again.

c.reset('module', `My module`);
c.log(`Welcome to 'module' namespace!`);

c.reset('module-task1', `Special task`);
c.log(`Initializing awesome...`);

c.reset('module-task2', `Task #2`);
c.log(`Washing dishes...`);
c.log(`Preparing table...`);

c.reset('module');
c.log(`I'm done`);

c.reset();
c.log(`I think 'My module' done with it!`);

It will output:

[My module] Welcome to 'module' namespace!
[My module » Special task] Initializing awesome...
[My module » Task #2] Washing dishes...
[My module » Task #2] Preparing table...
[My module] I'm done
I think 'My module' done with it!

namespaceNestingSymbol

String with character that is used to split namespace to names.

c.namespaceNestingSymbol = '-';// Default value
c.reset('first-second-thirdName');
c.log();
// Will output: [first » second » thirdName]

namespace

Array containing names data, that are sent to routers. Automatically set by c.reset.

models, outputs, routers

Built-in objects

RawModel, StdOutput, FileOutput, StdRouter

Built-in classes

What are models, outputs and routers?

Separation of these concerns in module makes it possible to keep structure of sending messages to any elements of user interface.

Models - such objects that are used to convert ...obj to data, that is used in majority of outputs.

Outputs - such objects that are used to print every message to expected place. You can also think about them as "views".

Routers - such objects that are used to send data to multiple outputs with any models. You can also think about them as "controllers".

By default there is c.routers.std that is instance of StdRouter.

Standard router has task to send data about every income message to c.outputs.std that is instance of StdOutput. That data is converted by c.models.raw that is instance of RawModel.

Standard solution

Default solution is bundled with StaticConsole: RawModel, StdOutput, FileOutput, StdRouter.

FileOutput is not initialized by default, but it must work. So you can print to c.outputs.std and instance of FileOutput at same time.

Test

npm test

or

ava --verbose test/MainTest.js

To make tests work, you'll probably need to have local copy of ava package in your node_modules.

Make your own solution

If you want to make your own model, output or router class, proceed to source code of module and copy standard solution's directories (RawModel, StdOutput, StdRouter).

Also try static-console with these plugins:

Outputs:

• ReactOutput
• DomOutput
• AlertOutput
