service. You need to obtain a valid token from your FontAwesome account and use it here. Please make sure not to expose this token publicly.\n\n## Local Deployment\n\n### Steps:\n\n1. Install the dependencies:\n\n```bash\nnpm install\n```\n\n2. Run Webpack to build the project:\n\n```bash\nnpm run prod\n```\n\n3. Run the application:\n\n```bash\nswift run\n```\n\nYou should now be able to see the application running at `localhost:8080`.\n\n## Production Deployment\n\nFor deploying to production, we recommend using [Render](https://render.com/).

It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.\n \"\"\"\n\n let matches = try Matcher.match(pattern: pattern, text: text)\n print(matches)\n }\n do {\n let pattern = #\"\\d+\"#\n let text = \"\"\"\n KIND DATE INSTITUTION AMOUNT\n ----------------------------------------------------------------\n CREDIT 03/01/2022 Payroll from employer $200.23\n CREDIT 03/03/2022 Suspect A $2,000,000.00\n DEBIT 03/03/2022 Ted's Pet Rock Sanctuary $2,000,000.00\n DEBIT 03/05/2022 Doug's Dugout Dogs $33.27\n DEBIT 06/03/2022 Oxford Comma Supply Ltd. £57.33\n \"\"\"\n\n let matches = try Matcher.match(pattern: pattern, text: text)\n print(matches)\n }\n do {\n let pattern = #\"((\\d{3})(?:\\.|-))?(\\d{3})(?:\\.|-)(\\d{4})\"#\n let text = \"\"\"\n Call 555-1212 for info\n \"\"\"\n\n let matches = try Matcher.match(pattern: pattern, text: text)\n print(matches)\n }\n }\n}\n" }, { "path": "package.json", "content": "{\n \"name\": \"swiftregex\",\n \"scripts\": {\n \"prod\": \"webpack --progress --config webpack.prod.js\",\n \"dev\": \"webpack --progress --config webpack.dev.js\"\n },\n \"dependencies\": {\n \"@createjs/easeljs\": \"2.0.0-beta.4\",\n \"@fortawesome/fontawesome-svg-core\": \"7.2.0\",\n \"@fortawesome/free-brands-svg-icons\": \"7.2.0\",\n \"@fortawesome/free-solid-svg-icons\": \"^7.0.0\",\n \"@fortawesome/pro-duotone-svg-icons\": \"6.1.1\",\n \"@fortawesome/pro-light-svg-icons\": \"6.1.1\",\n \"@fortawesome/pro-regular-svg-icons\": \"6.1.1\",\n \"@fortawesome/pro-solid-svg-icons\": \"6.1.1\",\n \"@popperjs/core\": \"2.11.8\",\n \"bootstrap\": \"5.3.8\",\n \"codemirror\": \"5.65.21\",\n \"pako\": \"2.1.0\",\n \"reconnecting-websocket\": \"4.4.0\",\n \"tippy.js\": \"6.3.7\"\n },\n \"devDependencies\": {\n \"autoprefixer\": \"10.5.0\",\n \"copy-webpack-plugin\": \"14.0.0\",\n \"css-loader\": \"7.1.4\",\n \"html-webpack-plugin\": \"5.6.7\",\n \"mini-css-extract-plugin\": \"2.10.2\",\n \"postcss\": \"8.5.14\",\n \"postcss-loader\": \"8.2.1\",\n \"sass\": \"1.99.0\",\n \"sass-loader\": \"16.0.8\",\n \"style-loader\": \"4.0.0\",\n \"webpack\": \"5.106.2\",\n \"webpack-bundle-analyzer\": \"5.3.0\",\n \"webpack-cli\": \"7.0.2\",\n \"webpack-merge\": \"6.0.1\"\n }\n}\n" }, { "path": "webpack.common.js", "content": "const path = require(\"path\");\nconst CopyWebbackPlugin = require(\"copy-webpack-plugin\");\nconst HtmlWebpackPlugin = require(\"html-webpack-plugin\");\nconst MiniCssExtractPlugin = require(\"mini-css-extract-plugin\");\n\nmodule.exports = {\n entry: {\n index: \"./Public/index.js\",\n },\n output: {\n globalObject: \"self\",\n filename: \"[name].[contenthash].js\",\n path: path.resolve(__dirname, \"Public/dist\"),\n publicPath: \"/\",\n clean: true,\n },\n module: {\n rules: [\n {\n test: /\\.scss$/,\n use: [\n {\n loader: MiniCssExtractPlugin.loader,\n },\n {\n loader: \"css-loader\",\n options: {\n url: false,\n sourceMap: true,\n importLoaders: 2,\n },\n },\n {\n loader: \"postcss-loader\",\n options: {\n sourceMap: true,\n postcssOptions: {\n plugins: [\"autoprefixer\"],\n },\n },\n },\n {\n loader: \"sass-loader\",\n options: {\n sourceMap: true,\n },\n },\n ],\n },\n {\n test: /\\.css$/,\n use: [\"style-loader\", \"css-loader\"],\n },\n {\n test: /\\.(woff|woff2|eot|ttf|otf)$/i,\n type: \"asset/resource\",\n },\n ],\n },\n plugins: [\n new CopyWebbackPlugin({\n patterns: [\n { from: \"./Public/images/*.*\", to: \"images/[name][ext]\" },\n { from: \"./Public/favicons/*.*\", to: \"[name][ext]\" },\n { from: \"./Public/error.html\", to: \"error.leaf\" },\n { from: \"./Public/robots.txt\", to: \"robots.txt\" },\n ],\n }),\n new HtmlWebpackPlugin({\n chunks: [\"index\"],\n filename: \"index.leaf\",\n template: \"./Public/index.html\",\n }),\n new MiniCssExtractPlugin({\n filename: \"[name].[contenthash].css\",\n }),\n ],\n};\n" }, { "path": "webpack.dev.js", "content": "const { merge } = require(\"webpack-merge\");\nconst common = require(\"./webpack.common.js\");\n\nmodule.exports = merge(common, {\n mode: \"development\",\n devtool: \"inline-source-map\",\n});\n" }, { "path": "webpack.prod.js", "content": "const { merge } = require(\"webpack-merge\");\nconst common = require(\"./webpack.common.js\");\nconst BundleAnalyzerPlugin =\n require(\"webpack-bundle-analyzer\").BundleAnalyzerPlugin;\n\nmodule.exports = merge(common, {\n mode: \"production\",\n devtool: \"source-map\",\n plugins: [\n new BundleAnalyzerPlugin({ analyzerMode: \"static\", openAnalyzer: false }),\n ],\n});\n" } ]
