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

[rmoskal]

This is when I try to

import { Button } from 'svelma'

This is the error:

(plugin svelte) ParseError: Identifier is expected
node_modules/svelma/src/components/Field.svelte
 95: <style lang="scss">
 96:   .field {
 97:     &.is-grouped {
         ^
 98:       .field {
 99:         flex-shrink: 0;
ParseError: Identifier is expected

This is my enviroment:

Now using node v13.5.0 (npm v6.13.4)

[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 git@github.com:Kiho/smelte-demo.git to run fine. The setup seems quite different though.

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!

[zakaria-chahboun]

The same issue i have!

[SumitBando]

Same issue!

[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 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,

          },
        ],
      ],
    }),

    // If you have external dependencies installed from

    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

};

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,
        });
      }
    },
  };
}

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

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.
