With the latest Desmos software upgrade, we have replaced the "Like" action with the "Reaction" one. This allows you to express a larger set of emotions regarding a post.

Adding your first reaction

To add a reaction to a post, the procedure is really easy.

The first thing that you need to do is to find a post that you want to react to. To do so you can use our explorer and browse though all the posts. Once you have find the one that you prefer, note its ID number.

Once you have the ID number of a post you would like to react to, open a new terminal window and execute the following command:

desmoscli tx posts add-reaction <post-id> <reaction> --from <your-key-name>

# Example
# desmoscli tx posts add-reaction 52 :+1: --from jack

Note that you can also use emojis while adding reactions, so the following command is valid too:

# Example
# desmoscli tx posts add-reaction 52 👍 --from jack

You will be asked to type the password you've chosen during the setup and after having inserted it properly you should see something like this:

height: 0
txhash: BFA3D9E508F1978135CB99AD07B975AB475AF8DD796C22D1B0984863B0ADACA9
code: 0
data: ""
rawlog: '[{"msg_index":0,"success":true,"log":"","events":[{"type":"message","attributes":[{"key":"action","value":"add_post_reaction"}]}]}]'
logs:
- msgindex: 0
  success: true
  log: ""
  events:
  - type: message
    attributes:
    - key: action
      value: add_post_reaction
info: ""
gaswanted: 0
gasused: 0
codespace: ""
tx: null
timestamp: ""
events: []

To make sure the transaction has been processed successfully, you can query it using the following command:

desmoscli query tx <hash> --output json

# Example
# desmoscli query tx BFA3D9E508F1978135CB99AD07B975AB475AF8DD796C22D1B0984863B0ADACA9 --output json

This will return you the JSON representation of the transaction itself.
