Quick Start

Follow the steps below to create and deploy your first serverless microservice in seconds.

1. Install via npm:

   $ npm install -g weblab-cli

2. Set-up your credentials

   $ weblab register
   
     Setup your Weblab Account
     -------------------------
   > Email: [email protected]
   > Username: (cristi)
   > Password: ***********
   
     Success: User registration complete.

   or if you already have a Weblab account just sign in with your credentials

   $ weblab login

3. Deploy a service

   In your Weblab microservice folder just run

   $ cd µservice
   $ wl deploy
   
     Service:
       hello-world-1.0.0
   
     Enpoints:
       GET - https://weblab.io/api/v1/run/cristi/hello-world-1.0.0/
   
     Uploading: ...
       success
   

4. List your services

   $ wl ls
   
   CONTAINER      | MICROSERVICE           | STATE      | STATUS    
   3a377aea233d   | hello-world-1.0.0      | running    | Up 2 hours
   3a48678fce52   | hal-1.0.0              | running    | Up 2 hours
   8bd1f4577575   | container-events-0.0.2 | running    | Up 3 weeks
   1c260895c73e   | weblab-fb-bot-1.0.0    | running    | Up 11 weeks
   

5. Inspect logs

   $ wl logs <container-id>

6. Remove a container

   $ wl rm <container-id>

7. Scale your microservice

   $ wl deploy -s 2
   
     Service:
       hello-world-1.0.0
     Scale:
       2 workers
   
     Enpoints:
       GET - https://weblab.io/api/v1/run/cristi/hello-world-1.0.0/
   
     Uploading: ...
       success
   
   $ wl ls
   
     CONTAINER      | MICROSERVICE           | STATE      | STATUS    
     ca5785b7aff2   | hello-world-1.0.0      | running    | Up 4 seconds
     6b0c33c7f206   | hello-world-1.0.0      | running    | Up 4 seconds
     3a48678fce52   | hal-1.0.0              | running    | Up 3 hours
     8bd1f4577575   | container-events-0.0.2 | running    | Up 3 weeks
     1c260895c73e   | weblab-fb-bot-1.0.0    | running    | Up 11 weeks
   

8. Run your microservice on your local machine

   $ wl local
   
     Service:
       hello-world-1.0.0
   
     Endpoints:
       GET - http://localhost:8991/
   
     Server:
       Started on port 8991
   

   Useful if you want to test your microservice localy before deploying to Weblab.

Examples

Hello World

package.json

{
  "name": "hello-world",
  "version": "1.0.0",
  "main": "index.js"
}

index.js

module.exports = function (req, res) {
  res.send('Hello, world!')
}

Upcoming Features

1. Realtime log streaming (scheduled for January 2017)

   $ wl logs -f <container-id>

2. Remote debugging (scheduled for February 2017)

   Use your favorite IDE (WebStorm / VS Code / etc.) to remote debug your microservice.

Development

Tests

$ npm test

Linter

We're using ESLint with Standard config

$ npm run lint

Unit tests

$ npm run unit

Git Hooks

• pre-commit hook to run linter before every commit

To install it just run in the project root directory:

$ ./tools/hooks/install.sh

If you want to skip the tests when you make a push just use the --no-verify flag. Example:

$ git commit --no-verify <remote> <branch>
