Glific - Two Way Open Source Communication Platform
Pre-requisites
There is level of understanding middle to advanced level. It is assumed that you know how to use a terminal, install things and have git and curl; for the backend, and for the frontend use install yarn and react.
- Software dependency - Postgres server
- Software dependency - Erlang / Elixir
- Backend - Download
- External service - Gupshup. <-- Get a Free trial to get API-key
- External service - Oban. <-- Needs 100 Euro per month
- Backend - Install certificate
- Backend - Config
- Frontend
1. Software dependency - Postgres server
- Download and start postgres server
For Postgres, for the development server, we default to using postgres/postgres/postgres as the username/password/machine name. This is configurable
We tested and developed against the following versions:
- postgres : v13.x, v14.x
2. Software dependency - Erlang / Elixir
- Install Elixir using asdf (check package versions below)
For Ubuntu users you also need to install the inotify-tools
package
We tested and developed against the following versions (please check .tool-versions in repository for the latest versons we are using):
- erlang : 25.3.2
- elixir : 1.14.5-otp-25
After installing asdf, install the Erlang and Elixir plugins.
asdf plugin add erlang https://github.com/asdf-vm/asdf-erlang.git
asdf plugin-add elixir https://github.com/asdf-vm/asdf-elixir.git
If you want to install the specific versions that were used for developing and testing:
asdf install erlang 25.3.2
asdf install elixir 1.14.5-otp-25
asdf global erlang 25.3.2
asdf global 1.14.5-otp-25
If you get any warnings for missing packages, just install them using apt and try again.
Note: It is important to use asdf to install Erlang and Elixir.
3. Backend - Download
git clone https://github.com/glific/glific
DO NOT run mix deps.get until the next steps are completed.
4. External service - Gupshup Create and link your Gupshup Account
Gupshup is an external service that connects to WhatsApp
You will need to do the following:
- Create a Gupshup Account
- Create an app and select Access API
- You can name it
NewNameHere
"GlificTest <-- Bot Name is already in use, then use anotherone" - Run the following command
cp config/dev.secret.exs.txt config/dev.secret.exs
- Now, in Gupshup, find your API Key: check the top right corner and click the profile picture or inside the curl sample message
- Enter your APP name and API Key in the dev.secret.exs file using any text editor.
5. External service - Oban Pro
Oban is a cron-like library. Glific depends 100% on job processing. Oban is required before running mix for Glific to operate.
For contributors: Please get in touch with the team on Discord and get a limited time key. Once they're provided to you, run:
mix hex.repo add oban https://getoban.pro/repo --fetch-public-key SHA256:4/abc/edf/gef+aIWPc --auth-key abcdefghi
with your keys
For production use: You must purchase license. When purchashing you must buy WEB+PRO . After you purchased Go to account and get this information and run this command in glific_backend
mix hex.repo add oban https://getoban.pro/repo --fetch-public-key SHA256:4/abc/edf/gef+aIWPc --auth-key abcdefghi
Replace public key "SHA256:4/abc/edf/gef+aIWPc" with your public key and auth key "abcdefghi" with your auth key.
Make sure your key is in the list
mix hex.repo list
Name URL Public key Auth key
oban https://getoban.pro/repo SHA256:4/abc/edf/gef+aIWPc abdedcqweasdj__KEY_AUTH__asdafasdf
If you see it twice, it will not work and fail, since Oban moved from public repository to private this is how an example of failing looks like
Name URL Public key Auth key
hexpm:oban https://repo.hex.pm/repos/oban SHA256:abc/edf/gef+aIWPc abdedcqweasdj__KEY_AUTH__asdafasdf
oban https://getoban.pro/repo SHA256:4/abc/edf/gef+aIWPc abdedcqweasdj__KEY_AUTH__asdafasdf
this is wrong, and you run mix deps.get it will try to fetch from public and ignore private and fail simply remove the public one
mix hex.repo remove hexpm:oban
Now check again
mix hex.repo list
Name URL Public key Auth key
oban https://getoban.pro/repo SHA256:4/abc/edf/gef+aIWPc abdedcqweasdj__KEY_AUTH__asdafasdf
6. Install certificate - Use SSL for frontend and backend
Before install also you need to create this SSL cert simila to this Go to glific_backend folder in the terminal console.
-
Install mkcert (https://github.com/FiloSottile/mkcert)
-
mkcert --install
-
mkcert glific.test api.glific.test
-
mkdir priv/cert
-
mv glific.test* priv/cert
-
cd priv/cert
-
ls -1
Check that glific.test+1-key.pem and glific.test+1.pem exists. -
Check port 4001
sudo lsof -n -i:4001 | grep LISTEN
should return nothing. -
Check hosts file
grep glific /etc/hosts
if returns nothing, then add these 2 lines to the hosts file 127.0.0.1 glific.test 127.0.0.1 api.glific.test
For Windows the steps is as follows:
-
Install mkcert (https://github.com/FiloSottile/mkcert)
-
Run the following command to install the local CA certificates:
mkcert --install
-
mkcert glific.test api.glific.test
-
mkdir priv/cert
-
move glific.test* priv/cert
-
cd priv/cert
-
dir
Check that glific.test+1-key.pem and glific.test+1.pem exists. -
Check port 4001
netstat -ano | findstr :4001
should return nothing. -
Check hosts file by
type %SystemRoot%\System32\drivers\etc\hosts | findstr glific
if returns nothing then add these two lines in your hosts file 127.0.0.1 glific.test 127.0.0.1 api.glific.test 127.0.0.1 postgres
7. Backend - Config
-
Run:
cp config/.env.dev.txt config/.env.dev
-
Run
source config/.env.dev
-
Run
mix deps.get
if this fails try firstmix local.hex --force
thenmix deps.get
if you see this error, then Oban key is wrong or failing. Check step 5. Or contact Oban.
❯ mix deps.get Failed to fetch record for 'hexpm:oban/oban_pro' from registry (using cache instead) This could be because the package does not exist, it was spelled incorrectly or you don't have permissions to it Failed to fetch record for 'hexpm:oban/oban_web' from registry (using cache instead) This could be because the package does not exist, it was spelled incorrectly or you don't have permissions to it ** (Mix) Unknown package oban_pro in lockfile
-
Run
mix setup
At this point you may get an error sayingpassword authentication failed for user "postgres"
, in which case, you need to configure the postgres server properly:
sudo -u postgres psql
ALTER USER postgres WITH PASSWORD 'postgres';
Exit the PostgreSQL terminal by typing \q
and pressing Enter. Run mix setup
again.
- Run
iex -S mix phx.server
- Inside the iex (you might need to hit enter/return to see the prompt)
- Update HSM templates by running the following command:
Glific.Templates.sync_hsms_from_bsp(1)
Now you can visit https://glific.test:4001
from your browser.
For Windows the steps is as follows:
-
Copy the file:
cp config/dev.secret.exs.txt config/dev.secret.exs
-
Copy the file:
cp config/.env.dev.txt config/.env.dev
. You may not need to edit the default values for DB URL and hostnames in this file if they look suitable for your needs. -
Run this on command prompt:
cd <path-to-glific-backend> set /p=DUMMY < config\.env.dev
Replace with the actual path to the glific_backend directory. This will load the environment variables from the .env.dev file.
-
Run
mix deps.get
if this fails try firstmix local.hex --force
thenmix deps.get
if you see this error, then Oban key is wrong or failing. Check step 5. Or contact Oban.
❯ mix deps.get Failed to fetch record for 'hexpm:oban/oban_pro' from registry (using cache instead) This could be because the package does not exist, it was spelled incorrectly or you don't have permissions to it Failed to fetch record for 'hexpm:oban/oban_web' from registry (using cache instead) This could be because the package does not exist, it was spelled incorrectly or you don't have permissions to it ** (Mix) Unknown package oban_pro in lockfile
-
Run
mix setup
-
Run
iex -S mix phx.server
-
Inside the iex (you might need to hit enter/return to see the prompt)
- Update HSM templates by running the following command:
Glific.Templates.sync_hsms_from_bsp(1)
Now you can visit https://glific.test:4001
from your browser.
8. Frontend - Install glific frontend
You cannot do much from the glific backend unless you are an API developer. To see Glific in its glory, please install Glific Frontend
Front end credentials
- Phone
917834811114
- Password
Secret1234!
Optional - Using NGROK
- Install ngrok
- Start ngrok to proxy port 4000:
- Start the backend server:
mix phx.server
$ ngrok http 4000 --host-header=glific.test:4000
(do this in a new window))- Remember the URL it assigns you, something like:
https://9f6a7c7822d2.ngrok.io
- Start the backend server:
- Goto the Settings Page
- On that page, Search for
Manage your Template messaging settings
and enable it - On same page, Search for
Callback URL / Link your Bot
- Enter your callback URL that ngrok gave you, add:
/gupshup
to the end. Something like:https://9f6a7c7822d2.ngrok.io/gupshup/
- Click
Set
. It should give you aCallback set successfully
message. If not, check the above steps.
