create-sequence

The Scramjet Cloud Platform sequence package initialization template ran by npm init scramjetorg/sequence <template-name>, for example:

npm init scramjetorg/sequence py-generator

The command above will not create any sequence directory, main files and package.json will be created in a place from which npm init ... command was executed. We advise to create sequence directory first and then execute npm init scramjetorg/sequence <template-name> from there. Then, if using typescript, use the npm install command.

All templates are in templates directory. If you won't use any <template-name> in npm init ... command, like when you execute init command like this:

npm init scramjetorg/sequence

the main file and package.json file will be created out of templates/default.

Running

Open a terminal in the folder of the selected template, then use:

# If you run this sample on Self Hosted Hub, please start it with command:
sth

# Run predeploy script:
npm run predeploy

# Deploy sequence to STH:
si seq deploy dist

And that's it, your code is running in the hub of your choice. :)

Need to install the following packages:
  github:scramjetorg/create-sequence

Ok to proceed? (y) y

Please type y to allow package installation, it is initial for npm init command to create files out of templates defined in this github repository.

In case of error:

$ npm init scramjetorg/sequence py-simple

Error: package.json already exists in current location

The Sequence initialization from the template must be done in the localization where there is no other package.json file. The command npm init scramjetorg/sequence does not include directory creation. Therefore, before you initiate sequence creation, create a new directory and run the npm init scramjetorg/sequence command from there.
