Do you know these 5 things about Vue Lifecycle Hooks?

Atharva Sharma — Thu, 11 Jun 2020 15:14:06 +0000

Vue Lifecycle Hooks are an example of the Template Method Design Pattern.
In the case of SSR, only the creation hooks are run on the server-side, all other hooks are run client-side.
Vue has an errorCaptured() hook and contrary to what you might believe, it does not capture all the errors thrown inside the component. Setting up a global error handler is suggested.
You can do programmatic lifecycle hook registration using $on or $once and pre-pending the hook name with hook:. Similarly, you can also listen to lifecycle hooks from children components.
There is a significant delay between the created() and the mounted() hook.

I cover all the above-mentioned points and more in my talk here.

Decentralised web apps: How to Deploy your web app onto IPFS with Fleek

Atharva Sharma — Sun, 22 Mar 2020 19:52:23 +0000

So I have been doing Frontend Development for a few years now and while I have tried different deployment solutions in the past, never did I come across a one-click solution for deploying to the InterPlanetary File System (IPFS).

Introducing Fleek

From local development to global deployment, Fleek is everything you need to build fast modern websites hosted on IPFS. Welcome to the new internet.

Vue + Fleek = Decentralised Magic?

Fleek provides an easy to set up solution for continous deployment using git. Once set up, it tracks for new changes to your repository and triggers deployments accordingly.
While almost all sites & popular frameworks are supported by Fleek, for the purpose of this tutorial I will be using Vue CLI 4 to set up a Vue.js app.

Gathering our tools

If you already know how to set up a Vue CLI project, you can directly jump to this section

Make sure that you have Node.js version 8.9 or above installed (8.11.0+ recommended). If not, you can do so by heading over here.
npm comes preinstalled with node.js

For installing Vue CLI 4, run the commands below:

npm install -g @vue/cli
# OR
yarn global add @vue/cli

Note: You need administrator privileges to execute these unless npm was installed on your system through a Node.js version manager (e.g. n or nvm).

You can check you have the right version with this command:

vue --version

Setting up the project

Let's call our app "decentralised-vue" and set up a new project by that name.

vue create decentralised-vue

Now select the options/preset of your choice, for this tutorial I am selecting these options:

After the project is set up:

cd decentralised-vue
npm run serve

Now let's go to localhost:8080.

Deploying Through Fleek

We now need to create a GitHub repository to store our project so Fleek can pick it up. You can create a repository and link it to our project using:

git remote add <name> <url>

git push <name>

The repository for this project can be found here. Now, we must go to Fleek.co, login and add a new site by clicking on the "Add new site" button.

Connect with GitHub:

Select the project repository:

Fleek will automatically determine the build commands:

Make sure that the build directory is dist:
You can also specify any environment variables if your project requires them.

Click "Deploy site" button, it will take a few mins.

Voila! Now your site is deployed.

You can see the project deployed here. You can also set a custom domain by going to Settings > Domain Management, you can also read about it here.
This is how easy it is to deploy apps onto IPFS using Fleek.
