Introduction

This repository contains files for developing and deploying the OWF InfoMapper application, developed using the Angular web framework.

The InfoMapper software can be installed as a static website, with configuration files and data to create a web application. New features made available in the general product are therefore available to each implementation of the tool.

The following table lists deployed websites and corresponding repositories.

Website	Content Generation Repository
Poudre Basin Information	owf-infomapper-poudre
StateMod Dataset viewer - under development	cdss-app-statemod-web

Repository Contents

The following folder structure is recommended for development. Top-level folders should be created as necessary. The following folder structure clearly separates user files (as per operating system), development area (owf-dev), product (InfoMapper), repositories for product (git-repos), and specific repositories for the product. Repository folder names should agree with GitHub repository names. Scripts in repository folders that process data should detect their starting location and then locate other folders using relative paths, based on the following convention. The InfoMapper folder structure follows the conventions for a single project Angular workspace. In the future, variations of InfoMapper such as embeddable single map (no application menus) may be implemented as a separate application, in which case the repository may be converted to a multi-project workspace.

Getting Started

Due to differences in environments, it is recommended that a single development environment is used. Do not mix the use of Git Bash and Cygwin on the same files on the same computer because they treat files differently with respect to line endings and executable permissions, which impacts Git.

Prerequisites:

Development and deployment of this Angular based web application requires the following tools:

• Node.js (version 10.x or higher)
  • Check which version of Node.js is installed by running node -v. To install Node.js, go to nodejs.org.

    NOTE: Although installing Node.js automatically installs npm, it is generally recommended to install npm by itself, so you're not stuck with whatever version came with node, and have more flexibility when upgrading it.

  • Node.js can be updated in a few different ways. Instructions can be found at phoenixmap.com.
  • To help prevent version lock-in, Node Version Manager (nvm) is a tool that can help keep different versions of Node separated in case many projects exist on the same machine. It is not required, but may make development easier.
• npm (version 5.5.1 or higher):
  • Check which version of npm is installed by running npm -v.
  • To update npm run npm install npm@latest -g.

Although the Angular CLI (Command Line Interface) is not required to run the InfoMapper per se, it is still recommended to install it globally using npm. This way, the ng command can be used anywhere on command line. When the InfoMapper application is installed, it will be using the locally installed Angular CLI.

• Angular CLI (latest version):
  • Install by running npm install -g @angular/cli.
  • As of version 4.2.0, the InfoMapper uses Angular 14.

Installing the InfoMapper Software

Currently, the InfoMapper is installed by cloning the source repository into the git-repos folder. Change to git-repos and execute:

git clone https://github.com/OpenWaterFoundation/owf-app-infomapper-ng.git

NOTE: If installing the application's dependencies for the first time, a developer needs to be authenticated to install the OWF Common Angular library. Visit the Authenticating to GitHub Packages section before continuing.

Run the following to install necessary software dependencies. This will install the OWF Common Angular library and required third-party packages.

If the primary developer, run the following commands that uses the dependencies from the package.json file:

cd infomapper
npm install --legacy-peer-deps

If a secondary developer, run the following commands that uses the dependencies from the package-lock.json file (the package-lock.json file must already exist):

cd infomapper
npm ci --legacy-peer-deps

NOTE: As of npm version 8, all warnings during an npm installation is considered a fatal error by default, and the installation will not be performed. The --legacy-peer-deps command option skips these warnings so the installation can finish. The InfoMapper relies on some packages that are not in active development, but still work with newer packages despite npm warnings. In the future, the goal is to either find a better, more up-to-date package, or remove the feature so that the InfoMapper can stay as free from these problematic packages as possible. The full list of these packages can be found in the Problematic dependencies section on the InfoMapper's README page.

The npm command may require several minutes. More information on the npm ci command can be found here.

Output in my configuration is:

> node ./bin/postinstall/script.js

Running the InfoMapper as a new application:

Once all prerequisites have been installed, follow these steps to run the InfoMapper as a new application. From a terminal, change directories into the desired directory to store the InfoMapper repository and run the following commands:

NOTE: The following options (SSH key & no SSH key) are both shown for clarity, but the GitHub website is good at determining whether a SSH key is being used or not on the system where the cloning is taking place. When the Code button is clicked and the Clone dropdown is displayed, there are 3 options to clone the repo: HTTPS, SSH, and GitHub CLI. GitHub will automatically choose the best option, and from past experience, whatever is shown should be used.

If a Github SSH key was created:

• git clone git@github.com:OpenWaterFoundation/owf-app-infomapper-ng.git

If no SSH key was created:

• git clone https://github.com/OpenWaterFoundation/owf-app-infomapper-ng.git

Once the cloning is complete:

• Run cd infomapper into the main InfoMapper folder.
• Run npm install to have npm download all necessary packages and dependencies used by the InfoMapper (this uses package.json).

The Angular application can be run locally, assuming that the desired app/ folder has been copied to the src/assets folder. Otherwise, the InfoMapper will display use the simple app-default/ files.

• ng serve (will not open a web browser tab) OR
• ng serve --open (will open a web browser tab)

The above may be slow the first time as code is compiled. After initial startup, changes to files will automatically result in a reload. View the website using the following URL:

http://localhost:4200

The default configuration and basic test data are distributed with InfoMapper in the src/assets/app-default folder and are typically removed from the distribution when deploying a full implementation.

Running the InfoMapper as an existing application

To update an existing version of the InfoMapper to the latest version, in a terminal, move into the infomapper/ folder of the repo and perform the following tasks:

• Confirm the current directory is infomapper/ by using ls, which should show the node_modules/ folder.
• Run rm -rf node_modules/ to recursively remove the folder and all nested folders. This will make sure that a clean install can be done later, with no chance of ornery files sticking around. Overall, this command will take a minute or two to complete.
• Run git status to check if other files have any changes. The main culprit is package-lock.json, as sometimes a small nested dependency version could change/update/etc. Use the git checkout -- package-lock.json command to revert the file back.
• Run git pull or git pull origin master to retrieve the updated repo.
• Run git checkout latest-stable to use the latest stable code. Otherwise, the master branch will possibly have more updated but less tested code.
• Run npm install to download the necessary packages from the InfoMapper's package.json file. This will take 5-9 minutes.
• Confirm the desired Angular version is being used by running ng version and viewing the top Angular CLI property. The version major number will describe the version, e.g. 13.2.1 is Angular 13. Something like the following will be shown:

**

**

Run either of the following two command to serve the InfoMapper:

• ng serve (will not open a web browser tab) OR
• ng serve --open (will open a web browser tab)

The above may be slow the first time as code is compiled. After initial startup, changes to files will automatically result in a reload. View the website using the following URL:

http://localhost:4200

Using InfoMapper with an Implementation Repository

InfoMapper can be used to implement an integrated website containing maps and other information. Currently, this is accomplished by creating a product folder, for example InfoMapper-MyRiver, and working with repositories for the software and implementation files. Using a repository for implementation files allows important work to be saved and tracked. In the future, a self-extracting executable to install InfoMapper may be provided. An example folder structure for a project at the Open Water Foundation is shown below. Note that the "product" folder in this case is "InfoMapper-MyRiver", whereas the "product" for InfoMapper software development is "InfoMapper".

C:\Users\user\                    User's home folder for Windows.
/C/Users/user/                    User's home folder for Git bash, corresponding to Windows user files.
/cygdrive/C/Users/user/           User's home folder for Cygdrive, corresponding to Windows user files.
  owf-dev/                        OWF (or any organization) development files.
    InfoMapper-MyRiver/           InfoMapper files for "MyRiver" website.
      git-repos/                  Folder for Git repositories.
=============== above this line is a recommendation ======================================
        owf-app-infomapper-ng/    InfoMapper software repository.
        owf-infomapper-myriver/   InfoMapper implementation files.

See the links above for example implementations of InfoMapper for examples of implementation repository file structures. Implementation generally involves copying files from the implementation folder into the src/assets InfoMapper folder, at which point the Angular application is able to use implementation files. Once the Angular application is started (see Running the InfoMapper section).

To use InfoMapper with an implementation, first check that the software is up to date by following instructions in Getting Started.

Deploying the Site to Amazon Web Servers

The site can be built in a dist folder for local testing by using the command

ng build --configuration production --aot=true --baseHref=. --configuration production --extractCss=true --namedChunks=false --outputHashing=all --sourceMap=false

The content of the dist folder can imitate a production build of the InfoMapper. To run the InfoMapper in its distributable form, navigate to the build-util folder and run the run-http-server-8000.sh file. In a web browser, type in http://localhost:8000/, then click on dist/ > infomapper to run the InfoMapper.

Once checked locally, deploy to the Amazon S3 site by running the following in the build-util folder using a Windows command shell:

copy-to-owf-amazon-s3.bat

For example, see the deployment script for the Poudre Basin Information InfoMapper implementation. Poudre Basin Information

The above can be run if Amazon Web Services credentials are provided. A batch file is used to overcome known issues running in Git Bash.
