Is it possible to use bash to install a nodejs package directly from github? Here’s why I want to do this: Please try and install directly from venom/master branch.
We’ve had some trouble updating the npmjs library release.
To install a Node.js package directly from a GitHub repository using Bash, you can use npm with the GitHub URL. Here’s a step-by-step guide on how to do this within a Pipedream workflow using a Bash step: 1. Create a Bash Step in Your Workflow: Add a new step in your Pipedream workflow and select “Run Bash” as the type. 2. Use npm to Install the Package: You can use the following Bash script to install a Node.js package directly from a GitHub repository. Replace username/repo with the appropriate GitHub repository path, and branch with the branch you want to install from (e.g., master). bash #!/bin/bash # Navigate to a temporary directory cd /tmp # Initialize a new Node.js project npm init -y # Install the package from the GitHub repository npm install github:username/repo#branch # Verify the installation npm list 3. Run the Bash Step: Execute the workflow to run the Bash script. This will install the Node.js package from the specified GitHub repository and branch. This approach uses npm to directly fetch and install the package from the specified GitHub repository and branch, bypassing the need for a release on npmjs. Make sure to replace username/repo and branch with the correct values for your specific use case.
and then in the sequence can I add a nodejs step and use this library that was installed via bash?
You can indeed add a Node.js step in your Pipedream workflow after a Bash step. However, it’s important to note that any libraries or packages installed in a Bash step won’t be directly available in a Node.js step. Each step in a Pipedream workflow runs in its own isolated environment. If you need to use a specific Node.js library, you can import it directly in your Node.js step using the import statement. Pipedream supports using any npm package in Node.js steps, so you can include the library you need by importing it at the top of your Node.js code. Here’s an example of how you can add a Node.js step and use a library: ```
import { axios } from “@pipedream/platform”; export default defineComponent({ async run({ steps, $ }) { // Your Node.js code here console.log(“This is Node.js code”); $.export(“test”, “Some test data”); return “Test data”; }, });
Is it possible for me to run nodejs code inside a bash step? What is the best way to do this in pipedream?
Running Node.js code directly inside a Bash step is not supported in Pipedream. Bash steps are designed to execute Bash scripts, and they do not have the capability to run Node.js code. However, you can run Node.js code in a separate Node.js step within the same workflow. Here’s how you can achieve this in Pipedream: 1. Create a Node.js Step: Add a new step in your workflow and select “Run Node.js code”. You can write any Node.js code here, use npm packages, and perform any operations you need. 2. Create a Bash Step: Add another step for Bash if you need to execute Bash scripts. You can pass data between the Node.js and Bash steps using Pipedream’s step exports. 3. Share Data Between Steps: Use step exports to share data between your Node.js and Bash steps. For example, you can export data from the Node.js step and access it in the Bash step using the $PIPEDREAM_STEPS environment variable. Here’s a simple example of how you might structure your workflow: - Node.js Step: export default defineComponent({ async run({ steps, $ }) { const data = { message: "Hello from Node.js" }; $.export("nodeData", data); }, }); - Bash Step: ```
bash # Access data exported from the Node.js step echo “Node.js says: $(echo $PIPEDREAM_STEPS | jq -r .nodeData.message)”
What are the main reasons to use a step bash in pipedream?
Using a Bash step in Pipedream can be beneficial for several reasons: 1. Quick Scripting: Bash is a powerful scripting language, and if you’re already familiar with it, you can quickly write scripts to automate tasks without needing to learn a new language. 2. Command-line Utilities: You can leverage the vast array of command-line utilities available in Unix-like systems directly within your workflows. This includes tools like grep, awk, sed, and more. 3. Curl Requests: Bash steps can be used to make HTTP requests using curl, which is useful for interacting with APIs or web services directly from the command line. 4. Data Manipulation: You can perform text processing and data manipulation using Bash’s built-in tools, which can be handy for transforming data between steps in a workflow. 5. Environment Variables: Bash steps allow you to access and use environment variables, which can be useful for managing configuration and secrets within your workflows. 6. Integration with Other Steps: You can share data between Bash steps and other steps in your workflow, allowing for seamless integration and data flow. For more information on using Bash in Pipedream, you can refer to the Bash documentation.
We mostly use bash steps to do stuff in the /tmp/... directory and run various CLI tools.
Here’s an example of installing a CLI tool from git:
curl -L -s -O "https://github.com/databricks/cli/releases/download/v0.205.2/databricks_cli_0.205.2_linux_amd64.zip"
unzip -q "databricks_cli_0.205.2_linux_amd64.zip"
chmod +x ./databricks
cp ./databricks /tmp/bin
I’m pretty sure you could just download your library from GitHub, save it in the /tmp/ directory, and load it as a local package in a node.js code step.
And theoretically, you don’t even need bash to do any of that.
