Following the current quick start in the readme I get a plugin svelte) ParseError: Identifier is expected about svelma

[graciasc]

npm install import autoPreprocess from 'svelte-preprocess';

import autoPreprocess from 'svelte-preprocess'; for your rollup config

Also add these to the postcss()

      extract: true,
      minimize: true,
      use: [
        [
          "sass",
          {
            includePaths: ["./node_modules", "./node_modules/bulma", "./src"],
          },
        ],
      ],

Should look something like this:

import svelte from "rollup-plugin-svelte";
import resolve from "@rollup/plugin-node-resolve";
import commonjs from "@rollup/plugin-commonjs";
import livereload from "rollup-plugin-livereload";
import autoPreprocess from 'svelte-preprocess';
import { terser } from "rollup-plugin-terser";
import postcss from "rollup-plugin-postcss";
const production = !process.env.ROLLUP_WATCH;

export default {
  input: "src/main.js",
  output: {
    sourcemap: true,
    format: "iife",
    name: "app",
    file: "public/build/bundle.js",
  },
  plugins: [
    svelte({
      // enable run-time checks when not in production
      dev: !production,
      // we'll extract any component CSS out into
      // a separate file - better for performance
      css: (css) => {
        css.write("public/build/bundle.css");
      },
      preprocess: autoPreprocess(),
      emitCss: true,
    }),
    postcss({
      extract: true,
      minimize: true,
      use: [
        [
          "sass",
          {
            includePaths: ["./node_modules", "./node_modules/bulma", "./src"],
          },
        ],
      ],
    }),

    // If you have external dependencies installed from
    // npm, you'll most likely need these plugins. In
    // some cases you'll need additional configuration -
    // consult the documentation for details:
    // https://github.com/rollup/plugins/tree/master/packages/commonjs
    resolve({
      browser: true,
      dedupe: ["svelte"],
    }),
    commonjs(),

    // In dev mode, call `npm run start` once
    // the bundle has been generated
    !production && serve(),

    // Watch the `public` directory and refresh the
    // browser on changes when not in production
    !production && livereload("public"),

    // If we're building for production (npm run build
    // instead of npm run dev), minify
    production && terser(),
  ],
  watch: {
    clearScreen: false,
  },
};

function serve() {
  let started = false;

  return {
    writeBundle() {
      if (!started) {
        started = true;

        require("child_process").spawn("npm", ["run", "start", "--", "--dev"], {
          stdio: ["ignore", "inherit", "inherit"],
          shell: true,
        });
      }
    },
  };
}

The same issue i have!

[SumitBando]

Same issue!

[mihaimiculescu]

Have you installed and configured sass?

[rmoskal]

Thanks for responding. I get this when I run node-sass -v. Does that seem right?

Now using node v13.5.0 (npm v6.13.4)
 rob  ~  node-sass -v
node-sass 4.13.1 (Wrapper) [JavaScript]
libsass 3.5.4 (Sass Compiler) [C/C++]
 rob  ~  

Another piece of information I can get [email protected]:Kiho/smelte-demo.git to run fine. The setup seems quite different though.

[mihaimiculescu]

Personally, I use dart-sass
My rollup.config.js:

import svelte from 'rollup-plugin-svelte';
import resolve from 'rollup-plugin-node-resolve';
import commonjs from 'rollup-plugin-commonjs';
import autoPreprocess from 'svelte-preprocess';
import postcss from 'rollup-plugin-postcss';
import livereload from 'rollup-plugin-livereload';
import { terser } from 'rollup-plugin-terser';
import rollup_start_dev from './rollup_start_dev';

const production = !process.env.ROLLUP_WATCH;

export default {
	input: 'src/main.js',
	output: {
		sourcemap: true,
		format: 'iife',
		name: 'app',
		file: 'public/bundle.js'
	},
	plugins: [
		svelte({
			// enable run-time checks when not in production
			dev: !production,
			// we'll extract any component CSS out into
			// a separate file — better for performance
			css: css => {
				css.write('public/bundle.css');
			},
			preprocess: autoPreprocess(),
                        emitCss: true
		}),
    		postcss({
      		extract: true,
      		minimize: true,
      		use: [
        		['sass', {
          			includePaths: [
            					'./node_modules',
						'./node_modules/bulma',
	    					'./src'
          				      ]
        			}]
      		     ]
    		}),

		// If you have external dependencies installed from
		// npm, you'll most likely need these plugins. In
		// some cases you'll need additional configuration —
		// consult the documentation for details:
		// https://github.com/rollup/rollup-plugin-commonjs
		resolve({
			browser: true,
			dedupe: importee => importee === 'svelte' || importee.startsWith('svelte/')
		}),
		commonjs(),
		
		// In dev mode, call `npm run start:dev` once
		// the bundle has been generated
		!production && rollup_start_dev,

		// Watch the `public` directory and refresh the
		// browser on changes when not in production
		!production && livereload('public'),

		// If we're building for production (npm run build
		// instead of npm run dev), minify
		production && terser()
	],
	watch: {
		clearScreen: false
	}
};

Also my rollup_start_dev.js :

import * as child_process from 'child_process';

let running_dev_server = false;

export default {
	writeBundle() {
		if (!running_dev_server) {
			running_dev_server = true;
			child_process.spawn('npm', ['run', 'start:dev'], { stdio: ['ignore', 'inherit', 'inherit'], shell: true });
		}
	}
};

You should proceed with caution: add code block by block until you get rid of errors and you get the expected result
You also probably will need to instal more npm modules.
My package.json:

{
  "name": "svelte-app",
  "version": "1.0.0",
  "scripts": {
    "build": "rollup -c",
    "dev": "rollup -c -w",
    "start": "sirv public --single --host 0.0.0.0",
    "start:dev": "sirv public --single --dev --host 0.0.0.0 --port 5000"
  },
  "devDependencies": {
    "rollup": "^1.31.0",
    "rollup-plugin-commonjs": "^10.1.0",
    "rollup-plugin-livereload": "^1.0.4",
    "rollup-plugin-node-resolve": "^5.2.0",
    "rollup-plugin-postcss": "^2.0.6",
    "rollup-plugin-svelte": "^5.1.1",
    "rollup-plugin-terser": "^5.2.0",
    "sass": "^1.25.0",
    "svelte": "^3.18.2",
    "svelte-preprocess": "^3.4.0"
  },
  "dependencies": {
    "bulma": "^0.8.0",
    "sirv-cli": "^0.4.5",
    "svelma": "^0.3.2"
  }
}

Good luck!

Hi, there !
In a Sapper context, following the Svelma README didn't work properly for me..
I used: { scss } from '@kazzkiq/svelte-preprocess-scss'
and then I get a lot of warnings, especially from code inside Svelma components...

// root folder is /home/fe/chifoomix/site/web
/home/fe/chifoomix/site/web/node_modules/svelma/src/components    /Dialog/Dialog.svelte
Dialog has unused export property 'promise'. If it is for external reference only, please consider using `export const promise`
85:   // export let showClose = true
86:   let resolve
87:   export let promise = new Promise((fulfil) => (resolve = fulfil))
                 ^
88:   
89:   // TODO: programmatic subcomponents

here's my rollup config
rollup.config.txt

[zoulja]

Any chance to get correct, complete and properly tested Installation guide for beginners?

[abbychau]

@zoulja
this thread is quite old. could you post the specific error message during usage?

[RichyHBM]

@abbychau I think the issue is that with a fresh svelte setup, there is no sass support: https://github.com/sveltejs/template/blob/master/rollup.config.js yet by the looks of the above comments, sass is a requirement. It would be good for the setup guide was going from the above rollup config to a working svelma rollout config

[webdev23]

The install leads to many errors with Svelte": "^3.0.0, like (!) Plugin svelte: A11y: <a> element should have an href attribute (...).

Svelte": "^3.0.0, rollup.config.js that works for me.
