A string replace plugin for gulp
First, install gulp-replace as a development dependency:
npm install --save-dev gulp-replace
# or
yarn add --dev gulp-replaceThen, add it to your gulpfile.js:
const replace = require('gulp-replace');
const { src, dest } = require('gulp');
function replaceTemplate() {
return src(['file.txt'])
.pipe(replace('bar', 'foo'))
.pipe(dest('build/'));
};
// or replace multiple strings
function replaceTemplate() {
return src(['file.txt'])
.pipe(replace('bar', 'foo'))
.pipe(replace('baz', 'fuz'))
.pipe(dest('build/'));
};
exports.replaceTemplate = replaceTemplate;const replace = require('gulp-replace');
const { src, dest } = require('gulp');
function replaceTemplate() {
return src(['file.txt'])
// See https://mdn.io/string.replace#Specifying_a_string_as_a_parameter
.pipe(replace(/foo(.{3})/g, '$1foo'))
.pipe(dest('build/'));
};
exports.replaceTemplate = replaceTemplate;const replace = require('gulp-replace');
const { src, dest } = require('gulp');
function replaceTemplate() {
return src(['file.txt'])
.pipe(replace('foo', function handleReplace(match){ return match.reverse(); })
.pipe(dest('build/'))
};
exports.replaceTemplate = replaceTemplate;const replace = require('gulp-replace');
const { src, dest } = require('gulp');
function replaceTemplate() {
return src(['file.txt'])
.pipe(replace(/foo(.{3})/g, function handleReplace(match, p1, offset, string) {
// Replace foobaz with barbaz and log a ton of information
// See https://mdn.io/string.replace#Specifying_a_function_as_a_parameter
console.log('Found ' + match + ' with param ' + p1 + ' at ' + offset + ' inside of ' + string);
return 'bar' + p1;
}))
.pipe(dest('build/'));
};
exports.replaceTemplate = replaceTemplate;const replace = require('gulp-replace');
const { src, dest } = require('gulp');
function replaceTemplate() {
return src(['file.txt'])
.pipe(replace('filename', function handleReplace() {
// Replaces instances of "filename" with "file.txt"
// this.file is also available for regex replace
// See https://github.com/gulpjs/vinyl#instance-properties for details on available properties
return this.file.relative;
}))
.pipe(dest('build/'));
};
