Do the same with *flows_cred.json* and *package.json* for credentials and nodes installed in Palette. Detail on step 5. 12 | 13 | ## 1. Deploying Node-RED to Heroku 14 | [![Deploy](https://www.herokucdn.com/deploy/button.png)](https://heroku.com/deploy?template=https://github.com/hybuild-project/nodered-heroku) 15 | 16 | ## 2. Set up GitHub repo and Heroku app 17 | * Fork this GitHub repo. 18 | * Set GitHub as deploy source on Heroku setting. 19 | * Enable Automatic Deployment, so that every time any file is pushed to GitHub repo, Heroku will rebuild Node-RED with updated files. 20 | 21 | ## 3. Password protect the flow editor 22 | Set username and password for Node-RED Flow Editor: 23 | * **NODE_RED_USERNAME** - the username to secure the Flow Editor with 24 | * **NODE_RED_PASSWORD** - the password to secure the Flow Editor with 25 | 26 | ## 4. Access Node-Red on Cloud 27 | * Flow Editor - [nodered-on-cloud.herokuapp.com/editor](https://nodered-on-cloud.herokuapp.com/editor) 28 | * Dashboard UI - [nodered-on-cloud.herokuapp.com/ui](https://nodered-on-cloud.herokuapp.com/ui) 29 | * Home page - [nodered-on-cloud.herokuapp.com](https://nodered-on-cloud.herokuapp.com) 30 | 31 | ## 5. Export all flows, credentials and installed nodes 32 | ### Manual mode (original) 33 | * In Editor, to export *flows.json*, click hamburger icon `☰` (top right), click Export, choose tab "All flows", then Download. 34 | * To export all the other files, browse the /app folder, e.g., with this [flow](https://flows.nodered.org/flow/44bc7ad491aacb4253dd8a5f757b5407) or the [modified version](utils/file-explorer-flow.json), and download all files. 35 | * Push *flows.json*, *flows_cred.json*, *package.json* to GitHub, so that Node-RED is rebuilt with the latest files at Heroku restart. 36 | ### Alternative mode (recommended) 37 | * Use the `SAVE` Inject node in the [first flow](utils/save-all-changes-flow.json) to directly push all files to GitHub. 38 | 39 | ![SAVE](public/images/save-button.png) 40 | 41 | ## Some included nodes 42 | * Dashboard UI - node-red-dashboard 43 | * MQTT - node-red-contrib-aedes 44 | * Blynk Cloud - node-red-contrib-blynk-ws 45 | * Email - node-red-node-email 46 | * Telegram - node-red-contrib-telegrambot-home 47 | * InfluxDB, MongoDB, Modbus, OPC UA, Netatmo, PostgresSQL, Wordmap, etc. 48 |

Node-RED in Heroku

Node-RED provides a browser-based editor that makes it easy to wire together flows that can be 41 | deployed to the runtime in a single-click.

42 |

The version running here has been customised for Heroku.

43 |

More information about Node-RED, including documentation, can be found at nodered.org.

64 |
65 |

Customising the Node-RED instance

66 |

This template instance of Node-RED is enough to get you started creating flows. 67 |

68 |

You may want to customise it for your needs, 69 | for example replacing this introduction page with your own, adding http authentication to the 70 | flow editor or adding new nodes to 71 | the palette.

72 |

73 |

Password protect the flow editor

74 |

By default, the editor is open for anyone to access and modify flows. To password-protect the 75 | editor:

76 |

Add the following user-defined variables.

77 |
    78 |
  • NODE_RED_USERNAME - the username to secure the editor with
    • 79 |
  • NODE_RED_PASSWORD - the password to secure the editor with
    • 80 |
81 |

Adding new nodes to the palette

82 |
    83 |
  • There is a growing collection of additional nodes that can be added to the Node-RED editor. 84 | You can search for available nodes in the Node-RED library.
    • 86 |
  • The required node package are added in the file package.json to the 87 | dependencies section. The format is: 88 | 
    "node-red-package-name":"x.y.x"
    where x.y.z is the desired 89 | version number. 90 |
    • 91 |
  • 92 | See next section to save the added nodes. 93 |
    • 94 |
95 |

Saving deployed flows and installed nodes

96 |
    97 |
  • Heroku doesn't automatically save flows, credentials and installed nodes, so they may be 98 | lost when dynos are restarted. To overcome this, changes must be pushed to GitHub so as 99 | Node-RED is rebuilt correctly with the changed files when Heroku restarts.
    • 100 |
  • To do this, use the SAVE Inject node in the first Flow to push 101 | flows.json, flows_cred.json and package.json to 102 | GitHub, after new flows are deployed and/or new nodes installed into the Palette. 103 |
    • 104 | 105 |
106 |

Upgrading the version of Node-RED

107 |
    108 |
  • This boilerplate is configured to grab the latest stable release of Node-RED whenever the 109 | application is pushed into Heroku.
    • 110 |
111 |

Changing the static web content

112 |
    113 |
  • The page you are reading now is served as static content from the application. This can be 114 | replaced with whatever content you want in the public directory.
    • 115 |
116 |

Remove static web content and serve the flow editor from the root path

117 |
    118 |
  • In the file settings.js, delete the httpStatic and 119 | httpAdminRoot entries. 120 |
