Can't get ESLint recognize and running using Gulp. Code for gulpfile.js is:
"use strict";
var gulp = require('gulp');
var connect = require('gulp-connect'); //Runs a local dev server
var open = require('gulp-open'); //Open a URL in a web browser
var browserify = require('browserify'); // Bundles JS
var reactify = require('reactify'); // Transforms React JSX to JS
var source = require('vinyl-source-stream'); // Use conventional text streams with Gulp
var concat = require('gulp-concat'); //Concatenates files
var lint = require('gulp-eslint'); //Lint JS files, including JSX
var config = {
port: 9005,
devBaseUrl: 'http://localhost',
paths: {
html: './src/*.html',
js: './src/**/*.js',
css: [
'node_modules/bootstrap/dist/css/bootstrap.min.css',
'node_modules/bootstrap/dist/css/bootstrap-theme.min.css'
],
dist: './dist',
mainJs: './src/main.js'
}
}
//Start a local development server
gulp.task('connect', function() {
connect.server({
root: ['dist'],
port: config.port,
base: config.devBaseUrl,
livereload: true
});
});
gulp.task('open', ['connect'], function() {
gulp.src('dist/index.html')
.pipe(open({ url: config.devBaseUrl + ':' + config.port + '/'}));
});
gulp.task('html', function() {
gulp.src(config.paths.html)
.pipe(gulp.dest(config.paths.dist))
.pipe(connect.reload());
});
gulp.task('js', function() {
browserify(config.paths.mainJs)
.transform(reactify)
.bundle()
.on('error', console.error.bind(console))
.pipe(source('bundle.js'))
.pipe(gulp.dest(config.paths.dist + '/scripts'))
.pipe(connect.reload());
});
gulp.task('css', function() {
gulp.src(config.paths.css)
.pipe(concat('bundle.css'))
.pipe(gulp.dest(config.paths.dist + '/css'));
});
gulp.task('lint', function() {
return gulp.src(config.paths.js)
.pipe(lint({config: 'eslint.config.json'}))
.pipe(lint.format());
});
gulp.task('watch', function() {
gulp.watch(config.paths.html, ['html']);
gulp.watch(config.paths.js, ['js', 'lint']);
});
gulp.task('default', ['html', 'js', 'css', 'lint', 'open', 'watch']);
and eslint.config.json is :
{
"ecmaFeatures": {
"jsx": true
},
"env": {
"browser": true,
"node": true,
"jquery": true
},
"rules": {
"quotes": 0,
"no-trailing-spaces": 0,
"eol-last": 0,
"no-unused-vars": 0,
"no-underscore-dangle": 0,
"no-alert": 0,
"no-lone-blocks": 0
},
"globals": {
jQuery: true,
$: true
}
}
and finally package.json dependencies are:
"dependencies": {
"bootstrap": "^3.3.7",
"browserify": "^14.1.0",
"gulp": "^3.9.1",
"gulp-concat": "^2.6.1",
"gulp-connect": "^5.0.0",
"gulp-eslint": "^3.0.1",
"gulp-open": "^2.0.0",
"jquery": "^3.1.1",
"reactify": "^1.1.1",
"vinyl-source-stream": "^1.1.0"
}
What can I edit to get one or more of the three files to work?
As you can read at https://github.com/adametry/gulp-eslint#optionsconfigfile
Key name has changed to configFile
Please rename eslint.config.json filename to .eslintrc .
Then change the lint gulp task as following.
gulp.task('lint', function() { return gulp.src(config.paths.js) .pipe(lint.format()); });
