Tiny module for buffering and redirecting console methods.
$ npm install concap --save
var concap = require('concap');
console.log('1');
concap.hijack();
console.log('3'); // `3` captured here
concap.restore();
console.log('2');
concap.flush(); // and flushed here
will output:
1
2
3
warn callvar concap = require('concap');
concap.hijack();
console.warn('buffered', /output/, function sir(){});
concap.restore();
var calls = concap.getClean();
console.log(calls);
console.log(concap.render(calls));
will show:
[ { method: 'warn', args: [ 'buffered', /output/, function sir(){} ] } ]
console.warn("buffered", /output/, function sir(){});
It is also possible to make console instance to use it locally:
var concap = require('concap');
var local = new concap.Console();
var calls = [];
local.on('data', e => calls.push(e));
local.warn('today is:', new Date());
console.log(concap.render(calls, { object: 'this.cons' }));
will generate:
this.cons.warn("today is:", new Date(1452619284325));
var concap = require('./');
var res = concap.capture(() => template.apply({
head: '<link rel="icon" type="image/x-icon" href="https://assets-cdn.github.com/favicon.ico">',
body: `<p>This is just an example of parkur ninja style.</p>
<p>Please don't repeat this by yourself: it's dangerous!</p>`
}));
console.log(inject(res, `<script>\n${concap.render(concap.getClean())}\n</script>`));
function template() {
console.warn('Wake up! You using deprecated template!');
return `<html>
<head>${this.head||''}</head>
<body>${this.body||''}</body>
</html>`;
}
function inject(html, log) {
return html.replace(/(<\/body>\s*)?(<\/html>\s*)?$/, m => log + m);
}
<html>
<head><link rel="icon" type="image/x-icon" href="https://assets-cdn.github.com/favicon.ico"></head>
<body><p>This is just an example of parkur ninja style.</p>
<p>Please don't repeat this by yourself: it's dangerous!</p><script>
console.warn("Wake up! You using deprecated template!");
</script></body>
</html>
