gulp-trycatch-closure

Enclose JS files content with a "try ... catch" statement.

It allows to easily catch errors on development.

Install

Install gulp-trycatch-closure using NPM, as a development dependency:

npm install --save-dev gulp-trycatch-closure

Usage

var gulp = require('gulp'),
    concat = require('gulp-concat'),
    trycatch = require('gulp-trycatch-closure');
 
gulp.task('build', function() {
    // Get all JS files
    return gulp.src(['src/js/*.js'])
        // Enclose their content with a try ... catch statement
        .pipe(trycatch())
        // Concat
        .pipe(concat('build.js'))
        // Send to destination
        .pipe(gulp.dest('dist/'));
});

Usage with gulp-if

var gulp = require('gulp'),
    concat = require('gulp-concat'),
    ifif = require('gulp-if'),
    trycatch = require('gulp-trycatch-closure'),

    // Check if we're in dev env
    isDev = process.NODE_ENV !== 'production';

gulp.task('build', function() {
    return gulp.src(['src/js/*.js'])
        .pipe(ifif(isDev, trycatch()))
        .pipe(concat('build.js'))
        .pipe(gulp.dest('dist/'));
});

Change the way to log errors

You can pass to the trycatch function an object of options. Here are the available options with their default value:

• logger - Way to log the error, default is console.warn(e);

Example of resulting build file:

try {
  
    /* file content */
 
} catch (e) {
    console.warn(e);
}
