Loading Web Fonts with the Web Font Loader in Nuxt.JS

NuxtJS

Several years ago the consensus on font loading in the community was that, as a website loads, all fonts should be hidden until the correct resources have.

Now, let ‘s do it for Nuxt.JS. This is steps to configure:

  • Include webfontloader via npm install webfontloader --save
  • Add webFontLoader.js file to /plugins folder:
import WebFont from 'webfontloader';

WebFont.load({
  google: {
    families: ['Fira Sans:400,500,600,700:latin,vietnamese']
  }
});
  • Adjust nuxt.config.js:
plugins: [
  {src: '~/plugins/webFontLoader.js', ssr: false}
],

How to auto redirect Netlify site to HTTPS

Netlify

Netlify support two ways to config redirect rules for your Netlify site:

  1. Via _redirects file.
  2. Via netlify.toml file.

I prefer the second way because of limitation of the first one.

If you’re running a build command or site generator, the _redirects file should end up in the folder you’re deploying (the Publish directory in your settings)

From Netlify documentation

Just put below config into your netlify.toml file.

For more information, you can read it from https://www.netlify.com/docs/netlify-toml-reference/#redirects.

How to solve ‘ReferenceError: window is not defined’ when importing Vue plugin in Nuxt.JS

NuxtJS

I need to use Vue plugin named vue-flash-message in Nuxt.JS. I installed it via NPM and created file vue-flash-message.js in folder plugins.

import Vue from 'vue';
import VueFlashMessage from 'vue-flash-message';

Vue.use(VueFlashMessage);

Then I tried to run `npm run dev` to test whether the plugin works. But it doesn’t work.

The reason is the default mode of Nuxt is SSR. The variable window is only available in the browser, not on the server.

And I found the solution, I just change the file content like below:

import Vue from 'vue';

if (process.browser) {
  window.onNuxtReady(() => {
    const VueFlashMessage = require('vue-flash-message');
    Vue.use(VueFlashMessage);
  })
}

After that, it should work fine. You also apply the idea for other Vue plugins.

Note on migrating Spring Boot 1.5 to 2.0

Spring Framework Logo

1. Useful links
First of all, you should read recommended links:

2. Tips and solution for problems

  • Table ‘hibernate_sequence’ doesn’t exist

Solution: Add config spring.jpa.properties.hibernate.id.new_generator_mappings=false

  • Spring Boot 2.0 use HikariCP by default, so you should add config for HikariCP

Solution:

Add config

spring.datasource.hikari.max-lifetime={max-lifetime-value}
spring.datasource.hikari.idle-timeout={idle-timeout-value}

Note:
– Value for config must be in millisecond.
– spring.datasource.hikari.idle-timeout < spring.datasource.hikari.max-lifetime < database wait_timeout
– For MySQL/MariaDB, use query SHOW GLOBAL VARIABLES LIKE 'wait_timeout'; to get wait_timeout, this value is in second
– For example, database wait_timeout = 600 second, so I can assign value as below:
spring.datasource.hikari.max-lifetime=500000
spring.datasource.hikari.idle-timeout=400000

  • Use MariaDB driver for MariaDB instead of MySQL Driver

Solution:
Step 1: Remove MySQL Driver:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
Step 2: Add MariaDB Driver:
<dependency>
<groupId>org.mariadb.jdbc</groupId>
<artifactId>mariadb-java-client</artifactId>
<scope>runtime</scope>
</dependency>
Step 3: Change database connection URL: change from jdbc:mysql://... to jdbc:mariadb://...
