Prerequisites
- MongoDB 3.4+
- Node JS 6+
- Maven
Step 1: Download and Built the code
Saga is made up of several projects that can be used stand-alone or together. For this tutorial, we will be using the following projects to set up an instance of Saga and be able to start a new project:
- https://source.digital.accenture.com/projects/ST/repos/saga-library/browse
- https://source.digital.accenture.com/projects/ST/repos/saga-elasticsearch-action/browse
- https://source.digital.accenture.com/projects/ST/repos/saga-mongodb-provider/browse
- https://source.digital.accenture.com/projects/ST/repos/saga-openexchange-action/browse
- https://source.digital.accenture.com/projects/ST/repos/saga-sentence-breaker-stage/browse
- https://source.digital.accenture.com/projects/ST/repos/saga-spelling-alternatives-stage/browse
- https://source.digital.accenture.com/projects/ST/repos/saga-spellchecking-indexer/browse
- https://source.digital.accenture.com/projects/ST/repos/saga-entity-trainer/browse
- https://source.digital.accenture.com/projects/ST/repos/saga-action-framework/browse
- https://source.digital.accenture.com/projects/ST/repos/saga-server-parser/browse
- https://source.digital.accenture.com/projects/ST/repos/saga-server-ui/browse
Start by cloning each repository and building the projects in the previous order. From 1 to 10, can be build via Maven using the command:
The eleventh package can be build via Node:
Step 2: Load a Mongo database (Optional)
Step 3: Configuring the environment
Saga Server Parser configuration files are specified in the Configure Pipelines & Resource Providers section. If you change any of those files in the src/main/resources/ folder, you need to rebuild the project or transfer the files to the directory specified in the startup.bat.
For the UI, you need to check the file in config/env/development.js. The display name, "Saga" in this case, is the name the UI will show for the project, but, what it is important is the uri attribute of the db, this is the database that Saga will be using. In the snippet, the database in use will be "SagaDB", change it according to your preference. If you loaded a Mongo database in step 2, you must change "SagaDB" to the name of the database you loaded.
solutions: [
{
display: 'Saga',
db: {
uri: process.env.MONGOHQ_URL || process.env.MONGOLAB_URI || 'mongodb://' + (process.env.DB_1_PORT_27017_TCP_ADDR || 'localhost') + '/SagaDB',
options: {
keepAlive: 10000,
reconnectTries: 10
}, //Database info for patter matching server switch
host: process.env.DB_1_PORT_27017_TCP_ADDR || 'localhost',
port: 27017,
name: 'SagaDB', // Enable mongoose debug mode
debug: process.env.MONGODB_DEBUG || false
},
matcher: {
uri: 'http://localhost:8080/_saga'
}
}
