(HELP) Upgrading NPM in assets folder Phoenix Framework

ariandanim · January 10, 2021, 12:48am

My App Spec:

Erlang/OTP 23 [erts-11.1.5] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [hipe] [dtrace]
Elixir 1.11.3 (compiled with Erlang/OTP 23)
Phoenix 1.5.7
NPM version 7.3.0
Node Js version 15.5.0

when i try to access the assets folder then typing "npm install"it shows like this:

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!

Then i try to install node modules in assets folder typing "npm install --legacy-peer-deps"then show like this:

i am wondering what the the warn deprecated above, so i typed in assets folder "npm outdated"then shows like this:

webpack 4.41.5 4.41.5 5.12.2 node_modules/webpack assets
webpack-cli 3.3.12 3.3.12 4.3.1 node_modules/webpack-cli assets

Question is, does is safe if i upgrading my assets folder the NPM plugin?

Hello and welcome…

Yes it is, but as for all major changes, You need update configuration. This time it’s webpack going to version 5.

You might follow this post about PR to Upgrade to webpack 5

ariandanim · January 10, 2021, 4:54pm

Tkyou,
how i set for the first time create my App without editing manual the package ? or still should i edit manually?

kokolegorille · January 10, 2021, 5:29pm

I do it manually.

kokolegorille · January 10, 2021, 6:36pm

… with the help of this package.

You need to know that there might be some breaking changes when updating, and You need to configure those files…

assets/webpack.config.js

Be sure to follow PR update path

config/dev.exs

Update this part.

  watchers: [
    node: [
      "node_modules/webpack/bin/webpack.js",
      "--mode",
      "development",
      "--watch",
      "--watch-options-stdin",
      cd: Path.expand("../assets", __DIR__)
    ]
  ]

This is a simple example of ncu, from the assets folder.

$ ncu
Checking /...
[====================] 29/29 100%

 terser-webpack-plugin  ^5.1.0  →  ^5.1.1   
 webpack                5.12.1  →  5.12.3   

Run ncu -u to upgrade package.json

As You can see there are some minor changes, and it’s probably safe to run ncu -u. But if You see some majors changing… You need to check for configuration update.

This is not really Phoenix related, but by default it uses Webpack to bundle your assets.

ariandanim · January 14, 2021, 7:06pm

when i typed ncu in my assets folder is show nothing, only said command not found

kokolegorille · January 14, 2021, 8:10pm

You need to install it with

npm install -g npm-check-updates

ariandanim · January 15, 2021, 7:10pm

after i typed “npm install -g npm-check-updates”, then show like this:

[info] Running BlogWeb.Endpoint with cowboy 2.8.0 at 0.0.0.0:4000 (http)

when i tried typed “npm install”, the message showing like this:

Do i missing something steps? please help…

ariandanim · January 15, 2021, 7:17pm

Continue with my comment above…

i try typed “npm install --legacy-peer-deps” in my assets folder then show like this

added 56 packages, removed 320 packages, changed 73 packages, and audited 652 packages in 16s

56 packages are looking for funding

then i typed ncu, its showing like this:

[====================] 15/15 100%

All dependencies match the latest package versions

then i go to my main folder app and typing “mix phx.server” then showing error like this:

i don’t know what next… T_T

kokolegorille · January 15, 2021, 7:29pm

You really need to follow the PR I linked in my first post, because it won’t work otherwise…

You need to update config/dev.exs

And webpack.config.js

ariandanim · January 16, 2021, 1:42am

thankyou bro, its works, here my step according the PR

in my app folder config/dev.exs : i am remove this line

“node_modules/webpack/bin/webpack.js”,
“–mode”,
“development”,
“–watch-stdin”,

then replace with this line :

“node_modules/webpack/bin/webpack.js”,
“–mode”,
“development”,
“–watch”,
“–watch-options-stdin”,

after that i go to folder assets/package.json then i remove this line in the below dependencies:

"@babel/core": "^7.0.0",
"@babel/preset-env": "^7.0.0",
"babel-loader": "^8.0.0",
"copy-webpack-plugin": "^5.1.1",
"css-loader": "^3.4.2",
"hard-source-webpack-plugin": "^0.13.1",
"mini-css-extract-plugin": "^0.9.0",
"node-sass": "^4.13.1",
"optimize-css-assets-webpack-plugin": "^5.0.1",
"sass-loader": "^8.0.2",
"terser-webpack-plugin": "^2.3.2",
"webpack": "4.41.5",
"webpack-cli": "^3.3.2"

and replace with this line :

"@babel/core": "^7.x",
"@babel/preset-env": "^7.x",
"babel-loader": "^8.x",
"copy-webpack-plugin": "^6.x",
"css-loader": "^5.x",
"css-minimizer-webpack-plugin": "^1.x",
"mini-css-extract-plugin": "^1.x",
"sass": "^1.x",
"sass-loader": "^10.x",
"webpack": "^5.x",
"webpack-cli": "^4.x"

after that i go to assets/webpack.config.js i remove all the line then replace with this line

const path = require(‘path’);
const glob = require(‘glob’);
const MiniCssExtractPlugin = require(‘mini-css-extract-plugin’);
const CssMinimizerPlugin = require(‘css-minimizer-webpack-plugin’);
const CopyWebpackPlugin = require(‘copy-webpack-plugin’);

module.exports = (env, options) => {
const devMode = options.mode !== ‘production’;

return {
entry: {
  'app': glob.sync('./vendor/**/*.js').concat(['./js/app.js'])
},
output: {
  filename: '[name].js',
  path: path.resolve(__dirname, '../priv/static/js'),
  publicPath: '/js/'
},

module: {
  rules: [
    {
      test: /\.js$/,
      exclude: /node_modules/,
      use: {
        loader: 'babel-loader'
      }
    },
    {
      test: /\.[s]?css$/,
      use: [
        MiniCssExtractPlugin.loader,
        'css-loader',
        'sass-loader',
      ],
    }
  ]
},
plugins: [
new MiniCssExtractPlugin({ filename: '../css/app.css' }),
new CopyWebpackPlugin({
  patterns: [
    { from: 'static/', to: '../' }
  ]
})
],
optimization: {
minimizer: [
‘…’,
new CssMinimizerPlugin()
]
},
devtool: devMode ? ‘source-map’ : undefined
}
};

here is the link to make changes some file

ariandanim · January 16, 2021, 3:02am

i forgot to install this package in my assets folder

npm i css-minimizer-webpack-plugin
