@incrediblez/confy-tee v0.0.2

What is it?

This is a default Runner for confy-tee.

Used in npx calls, like

npx -p @incrediblez/confy-tee.common -p @incrediblez/confy-tee run --env=./somewhere/.env --config=./somewhere/config.json

See GIT Repo for details

Using with npx

Cool thing here is that you do not need to install any NPMs, configure any custom code, nothing.

You just run 1 "simple" command, and it gets the whole job done.

npm@5+ is the only requirement here.

NPX will manage all the NPMs for you, as long as you congigure the call properly.

Semantics of a call:

npx [-p packagename] run [--env=envfile] [--config=configfile]

Where:

• [-p packagename] section:
  • Is required.
  • Should always include -p @incrediblez/confy-tee, as a last package.
  • Can repeat as many times as needed.
  • Should include npm packages for ALL plugins your config relies on.
• [--env=envfile] section:
  • Is optional.
  • If provided - points to .env formatted file (TODO: Find the name of that format, there's one...)
• [--config=configfile] section:
  • Is required.
  • Should point to the Config, created manually or programmatically. See below for instructions on those.

Creating config manually

Top-level schema:

{
  "reads": [
    READ_PLUGINS_CONFIGS_OBJECTS
  ],
  "writes": [
    WRITE_PLUGINS_CONFIGS_OBJECTS
  ]
}

Readers schema:

• name
  • Unique name of the Setting, that needs to be processed.
  • Writers will lookup setting by that name (try to find the value, that Processor red for that Setting)
• plugin
  • String, representing plugin that should be used here.
  • Format: PLUGIN_FOLDER/PLUGIN_CLASS_NAME. F.e Common.HardcodedStringReader
• settings
  • Config, that is defined in your selected Plugin file.
  • Refer to the selected Plugin's README.md or Plugins.ts for details on which fields there are, and how to fill them in.
  • Can be Object or String.
• skip
  • Nullable field. Set that to true if you would like to skip that specific step from processing.

Example:

{
  "name": "SOME_SETTING",
  "plugin": "Common.HardcodedStringReader",
  "settings": "CONFIG_VALUE"
}

Writers schema:

• name
  • Unique name of the Setting, that needs to be processed.
  • Refers to the one of the names in Readers (reads).
• plugin
  • String, representing plugin that should be used here.
  • Format: PLUGIN_FOLDER/PLUGIN_CLASS_NAME. F.e Common.AppendEnvFileWriter
• settings
  • Config, that is defined in your selected Plugin file.
  • Refer to the selected Plugin's README.md or Plugins.ts for details on which fields there are, and how to fill them in.
  • Can be Object or String.
• write_name
  • The name, under which this setting will be recorded at the Target system.
  • Nullable field. If not provided - name will be used instead.
• skip
  • Nullable field. Set that to true if you would like to skip that specific step from processing.

Example:

{
  "name": "SOME_SETTING",
  "write_name": "SECRETLY_SECRET",
  "plugin": "Common.AppendEnvFileWriter",
  "settings": "./.dev.env"
}

Creating config programmatically

This option allows to get all the fancyness of TypeScript at your service. Like - strong typing, validations, and even JSDocs.

Once configs are created - you can

• Run them in Processor yourself. Just take a look at how it's done in core/runner.ts, or in the example below.
• Or export them to file (via f.e. JSON.stringify(MY_STRONGLY_TYPED_CONFIG)), and then run via npx (see above for example)

Small example of how-to do the Config programmatically:

import  dotenv from "dotenv"

// Include types and desired Plugins

// Via files (mostly dev)
// import { Config, Processor } from "../config-ur-gator/types/types"
// import {
//   AppendEnvFileWriterConfig,
//   HardcodedStringReaderConfig
// } from "../config-ur-gator/plugins/Common/Plugins"

// Via npm
import { Config, Processor} from '@incrediblez/confy-tee.types'
import {
  AppendEnvFileWriterConfig,
  HardcodedStringReaderConfig
} from '@incrediblez/confy-tee.common'

// Season it with any plugins you would like to use.
// import { MyCustomPlugin } from 'confy-tee.mycustomplugin'

const env = dotenv.config().parsed

// Compose a custom settings by TS
const MY_STRONGLY_TYPED_CONFIG: Config = {
  reads: [],
  writes: []
}

// Reads
const readThingOne: HardcodedStringReaderConfig = {
  plugin: 'Common.HardcodedStringReader',
  name:'SETTING_ONE',
  settings: 'SETTING_{{SOMETHING_SOMETHING}}'
}
MY_STRONGLY_TYPED_CONFIG.reads.push(readThingOne)

// Writes
const writeThingOne: AppendEnvFileWriterConfig = {
  plugin: 'Common.AppendEnvFileWriter',
  name: 'SETTING_ONE',
  settings: './.dev.env',
}
MY_STRONGLY_TYPED_CONFIG.writes.push(writeThingOne)

// process em all!
const processor = new Processor(MY_STRONGLY_TYPED_CONFIG, env)

// Set that if you're using direct files import, not npm. path here is Relative to 'processor.ts' file.
// processor.dangerouslySetCustompathForPLuginsDuringDevelopment('../plugins')

// processor.ValidateConfigs()
// processor.DryRun()
processor.Execute()

Environment, how to use it, and how it works?

Processor can work with plain env object (key-value pairs).

In core/runner.ts this is supplied via CLI parameter --env, and then red using dotenv into such object.

Then, when env object is available, and supplied to Processor, Processor will try to replace any placeholders it can find, in config object.

Placeholder mask is {{SEARCHTERM}}.

E.g.

• If in your env object you have something like SETTING=VALUE
• And in your config, one fo the fields have value SOMETHING_SOMETHING_{{SETTING}}
• Then processor will digest that into SOMETHING_SOMETHING_VALUE before running anything or usin ghte COnfig anyhow else.

Replacement is recursive, so you can use Terms in subfields on any level. As long as they're strings.

Where's my Plugins, dude?

Looking for a Plugin? Take a look at ../plugins in this repo.
